Paul -- Pegasus Racing carries dye penetrant (aka, "dye pen") crack testing materials. (Other companies do also, McMaster-Carr?) They will work on non-magnetic materials (including even non-metals is...

I didn't pay attention to your location when I posted this. McMaster-Carr will serve for reference info. I am sure you know (or will find) suppliers of spiral retaining rings in...

Also check the "eared" retaining rings themselves for best orientation when installing. Because they are typically stamped out of sheet stock, one side of the ring will have a quite sharp 90 degree...

Yep! It's a good idea to check (and record) everything before tearing it apart. I would measure and record camber & bump steer curves about every 1/4 inch of vertical suspension travel on both sides...

It might be worth contacting Hewland Classic via email for such technical info. They were very forthcoming re FT200 case material alloy for me several years ago. They confirmed the FT200 case is...

Several years ago I had Ivo Vinklarek repair weld an FT200 case and he did a great job. He runs a small business & has experience doing magnesium weld fab & repair for Colorado area vintage racers...

I also had a good experience with Chris re-doing a 3 piece wheel center for me. :thumbsup:

Can you post the name of the company near Indy that successfully did your electroless nickel plating? (Or, Private Message the info to me!) I had a source in Denver for many years, but...

I needed to have an old (1972-ish) 10 inch diameter sports-racer steering wheel re-covered because of seams separating. I got referred to Chris Scow @

Clarification (I hope) of Aussy Cleaver's comment above:

The angle of the top photo is a bit too straight-on to tell for sure, but this pump looks very similar to other (side-mounted) dry sump oil pumps, just driven from the nose of the jackshaft instead...

I think Phil's "...now where is that car?" may refer to the Chevron B20 that was for sale by Bill Scott Racing in 1978 (per the Chuck Sieber photo I posted from Oldracingcars.com website).

In Oldracingcars.com website on Chevron B20s there are some recently posted photos of a Chevron B20 FB (apparently fuel-injected, not Webers, judging by inclination of the trumpets) car that was for...

Tim --

Looks to me like you got it right, I just didn't follow your link right away & see the bright red nut photo illustrating how the parts are supposed to fit. :checkered:

How about getting the outside face of the wheels machined where the nut seats? That will provide the desired clearance for the safety pin without changing internal wheel to caliper/upright...

Jongbloed Wheels, perhaps?

Hi Nick,

I understand your lock-down dilemma. I am in a similar age range, but have the benefit of the car being in my home shop.

When the fuel vapours addiction overwhelms you, perhaps you...

Magic --

Another key factor to the clamping force is the thread pitch of the nut/spindle. It would be interesting to know what those are for the different cars in your shop. {I bet the "small...

A couple years ago I got some from VDS Engines (near Indy). Other possibilities would be Gordon Park @ Blue Sky Racing (BDAengines.com), or, Steve Jennings (sjenningsracing.com)
