Sorry if this is not the right thread area for it. Could not find one dedicated to selling/trading. I have a set of very nice pontiac shaft rocker arms thatProbe industries manufactured for Pacific performance racing. I bought them and found out when i opened them that one set had 2 intakes- instead of 1 intake- 1 exhaust.All the others were normal. Never installed or used. Still brand new. He told me to purchase either a crower or T&D rocker body and install it since everyone uses the same size shaft.This is more than im willing to do. im stuck - they are overkill for my street motor anyway.They are 1.6:1 ratio and have no visible flaws except the obvious wrong rocker installed.On the right motor - they will be worth the effort - not for my little 400 ... Can send pictures through email and point out the problem rocker. Asking $400 shipped. I have a ton of shims I'll even throw in so you can get your geometry right.PM for email.
