I'm in the process of installing a new DB-1 floor pan and have a question regarding rivet choice. The general consensus seem to be a 5/32" diameter counter-sunk head. Choice of steel vs. aluminum mandrel is in question (leaning toward aluminum) as well as grip length (no mention in all the threads I have searched). Another item I have to consider; current chassis holes are 1/8" (original?).
Checking my spares, I have roughly 150 1/8" diameter, 1/8" grip, all aluminum, pan head, Cherry-Q rivets. For grins, I trial fitted my new pan using a few of these 1/8"x1/8" rivets to find that these will easily hold the pan in place (while the bond dries right?).
I'm now faced with the question as what type of rivet to order/use. That is, do I order another 50 1/8"x1/8" to match my current inventory or the 5/32" diameter, 1/4" grip, steel mandrel, counter sunk, Cherry-Q (and drill out to 5/32 the 180+ chassis holes!)?
By the way, here's a great source for the rivets in question: http://www.rivetsinstock.com/
