70 5 lug disc brake thread

[PT'S 70 CST]

This is a new thread carried over from the one I had posted on the parts board for some 70,71 and 72 wheel studs. The parts book that I got this info from came from a buddy of mine that is a GM parts manager for 30+ years and he said in the book this part #3985844 clearly states that these studs are for 70 disc and 71,72 all. I have a 70 5 lug disc truck and have seen a few others and have been convinced that some of the late run 70 1/2 ton models that were highly optioned were offered with 5 lug disc. Here is some of the documentation that I have and will try and post pics of the info out of his parts book as soon as I get it. Here are four pages of options sheets from the GM dealership. I know there are a ton of yall who disagree about this but all I ask is to keep this thread clean.


Thanks PT
