Talking with Jim at Classic5speed.com again, He said a few of you guys would jump all over this. Are the parts I get from GM better than a fork I would get from Ground Up or other repo parts houses? Thanks

This is for my 70 chevelle.

In my personal opinion, things like that probably won't make much difference for aftermarket. pn. 3892632 70 454 all 396's from 66 up
and 3860005 for 71-72 454, and all 427's 66-69. Jason.
