Thanks all. Looks like Shockproof is the popular option.

Is there any concern with the solids in Shockproof clogging the oil pump, spray bars, etc?

I'm slightly reticent to post this question, but here goes ...

I see recommendations all over the place as to what oil to put in a Hewland dog box. Mine is a DGB with a 400 hp motor in front of...

A google search yielded this ... mentions he was a Vee enthusiast.

I don't necessarily have an opinion on the suitability of flipping a Hewland, but I do have one comment/question. Why would the shift pattern change due to flipping the trans? The linkage input on...

Driven (Joe Gibbs) and Brad Penn / Penngrade are two that folks in the vintage Porsche world seem to like.

I'd be curious to know more about the locking mechanism, and parts to make it, for a March 87C. Sounds like mine is similar to Dstarbuck's Lola. I googled and found a pic of another March showing a...

Interesting - this is very plausible, and it is consistent with the design of the snout (#29 in the diagram). So a design sort of a like a quick disconnect air hose with balls keeping the wheel nut...

I can't find any evidence of retention for #29 other than press fit. Which seems odd.

Correct that #29 is a separate part, presumably to allow its replacement as a higher wear part. But it appears to be just pressed into the hub. I looked at it for a few minutes today and can't find...

Some of you may have seen my threads over the past several years as I learned about keeping the wheelnuts on my GT racer that uses March 87C Indy uprights and hubs.

I noticed an interesting part...

Any suggestions on what to use for tire mounting lube? I see NAPA sells some stuff. Is that as good as any?

Rick Kirchner's thread showing the mods he did to the HF tire machine (pics have been re-added).

Ha, yeah that's what I'm prepared for based on what I've heard. No issues breaking out the welder. I figure at $50, I have a head start on building one from scratch :beer:

Thanks guys, appreciate the input. Sounds like the HF unit should be usable with some mods + the No-mar bar. Similar to what others have done, I'd plan to use PVC or similar to minimize the chance of...

Bumping to get input on people's experience mounting their own tires. Mine are 16" x 12" Hoosier radials. Do people mount this type of tire on their own? To be clear, I'm not looking to save a few...

The solid rear axle is a nice touch

Odd looking. My first thought until I looked closer was it's some kind of two seater.

Very cool. Do you know which car or color one? I noticed a few in the race. Do you know what the powerplant was?

Worth noting that DG300 and DGB dimensions are very similar. Gearset are *almost* interchangeable between the two gearboxes - the thickness of the gears is different by .020" or similar, and the dogs...

I don't personally have any info to contribute, but on one of the other car forums I'm on, there is a guy who worked on Warren Agor's Monza (see link to a pic below). Looks like similar wheels. Happy...

It sounds like you both own / work on mid 80s March Indys. What do you do for replacement rear hub / CV bolts? The ones that go through the hubs and CVs, and have the...

Wanted to comment on this as well. You're not the first one to mentioned the limited useful life of those bolts. Any information on a replacement since the original ones aren't available?

Thanks psc85c and tlracer - hadn't seen your responses until now.

Entirely possible my car has some 85C parts on it. The rotor hats look a little different than the ones pictures above - the...

Depending on how it's bent, an experienced wheel shop may be able to fix it. I had a Gotti wheel straightened a few years ago. At the time I couldn't find replacement rim halves. I think it cost me a...

I've been having a hard time finding a shop that can properly mount wide race tires. My car uses 16x12 BBS centerlock rims that have relatively small diameter mounting face 4 3/4" and 6 on 3 3/4"...

Anyone have a source for the internal safety clips? I have a set of four, but wouldn't mind having a spare or two. The vendor I bought mine from is no longer in business. Figured I'd ask before I...

I’m using the “vintage style” pins that install from the inner bore of the spindle. Here’s a pic using tlracer’s suggestion.
...

Thank you for pointing that out. Looks like you are correct. I've been using exactly that style pin on the rear center nuts (outboard of the nut in that case). i did a test fit this evening, and they...

Thanks for that. I measured a few of my wheels, fronts and rears. All seem to be about the same as you mention, I got 1 7/16". Shaving the front wheel inner faces doesn't seem like the right option...

The items in the "stack" include only the hubs, rotor hats, and wheels. The rotor hats are probably 1/8" (3 mm) or so, so not enough meat to make up the 2 mm I need to shorten the stack and make the...

Here's the best pic I can offer now (not home at the moment) - see below. With a wheel in place the nut is another 1-2 turns further outboard and mostly covers the holes in on the front spindles....

Can I get opinions on the following choices to make safety pins fit my front hubs (as a reminder the existing ones are mostly hidden by the nut on my car)?

Option 1 - turn down the outer face of...

I appreciate the offer! I hadn't planned on going, but now you've got me thinking ...

Thanks guys for the input as always. Responses below.

It's worth noting that the suspension parts in question are March 87C. The car is a GT car built in the 1990s using the 87C parts, which may...

I’m putting safety pins on my front centerlock wheels (I have them on the rears already). Problem is that at the moment, when the center nuts are torqued on the wheels, they cover the holes in the...

Bumping this for input on whether there should be a friction coating on the inner face of the center lock wheels, and also on he corresponding contact face on the brake rotor hats. Presumably to help...

If you have a cell made, make sure to follow the above advice. I had a cell bladder made by Fuel Safe a couple years ago to replace the badly deteriorated original one. They supposedly allowed extra...

Figured I'd update this wtih my findings. No dice on seals for the CP2293 3/4". Apparently the seals aren't available. I checked a number of suppliers, including an outfit in the UK that specializes...

I should have mentioned that Pegasus wasn't sure when I called. I also called Essex since they import AP/Lockheed parts, and they said rebuild kits are NLA. I find it hard to believe that I can't get...

Thanks for the responses, guys. Here is a pic of a CP2293 identical to the one I want to rebuild (the one in the pic is 5/8”, the one I need to rebuild is 3/4”). Will the 2623 rebuild kit work on...

I have an older 3/4" Lockheed master cylinder CP2293 style that I would like to rebuild. Apparently AP (successor to Lockheed) no longer makes the seals for this style master. Does anyone know of an...

I remember seeing those things run at Action Park in NJ when I was a kid. They had a go kart type track for mostly inexperienced drivers to rent rides in them. Even as a kid watching (not driving, I...

As a hobbyist with a modest level of experience making fiberglass parts, one thing I found when making a new nose and a diffuser for a GT car, I found it difficult to work quickly enough to finish...

Glad to hear you got the OP issue solved. Sharp looking car!

I race vintage Porsches that have a similar layout (engine in rear, oil tank in front). Usually by the time I've finished adding oil to the tank, it's made it's way to the engine and oil pump....

I'm in touch with the fabricator who used to work at Fabcar, and he suggested metal spraying the cup and re-machining back to size. I think I'll go with that, as the suspension arm appears in...

Interesting. Well it's possible I misspoke, but I gave that information based on an e-mail exchange with Dave (the owner). Perhaps he re-opened?

Fabcar. They were near Indy, but are no longer in business. I do have the contact info. for one of their fabricators. I'll reach out to him.

How about cad or zinc plating to put a few thousandths back on the ID of the bearing cups?
