SCORE!

Been looking for "original looking exhaust manifold studs off & on for some time. Most I find have a hex on the nut starter end. Not round like the OE studs.
Stumbled across these on Jegs, part# 90633. Cost $30.40 each to the door. I bought all 3 sets they had. The 2 black ones in the center are the new ones. Best I recall the nuts even look correct.

Nice! I think I'll be needing a set of those in due time as well, but it will be for 2.5 inch center dumps.

Cheers! TomK

That top one is factory curved to go around a steering box in a 57 chevy!

We always used 3/8" brass nuts and anti-seize on the threads so we could get the lead pipes off later when pulling the engine. Nice score. Now I just use hardened threaded rod.
