Yes, I have a pretty good knowledge on the late 60s early 70s gm muscle cars. I have a whole bunch of them!! lol
I hit yards hunting parts for my cars and pick up truck stuff when I find it. I want a 68 gmc jimmy one day! But they are pretty much rusted out around here.
I have a pretty big collection of big block truck stuff. The closest I have come to owning a pre-73 truck was my 72 ss 454 elcamino that my X got in the divorce two years ago!!
