Mark,
The chromies really woke that truck up!
Here is my
on installing the caps. I had a '93 Caprice wagon that I had a set of 20" Budniks that I ran in the nice weather months and I had a set of chrome 454SS truck wheels I wanted to use on the car for the winter. I refused to run the wheels without caps, so here's what I did.....
I took a set of 12mm lugnut covers (i.e. most all GM cars), ground the tops off of them (the hex part) and just stuffed them inside the 14mm lugnut caps. They are pretty much a friction fit, but if you wanted to silicone them together for a little bit of insurance I don't see why it would hurt. I wish I had pics of the process, but I don't.
If it's not clear on what I'm talking about, give me a holler and I can talk you through it. Specifically the 12mm GM lugnut covers I used were off of a Firebird and of course the 14mm lugnut covers were off of a Chevy pickup. Hope it works out for you!
