I don't know about the 10 bolt/12 bolt, m21/m22 issues Chuck, but I went to the Tn junkyard with Joey. The owner, probably in his 30's didn't have many teeth, but he did have a bunch of Camaro's and would not sell any of them.
Wish I'd taken a camera so I could show some of the odd cars n parts I saw that day...I seem to recall a Rambler with Yenko stripes on it
A tiny car with a 512 block & alum heads.
It was a good day & I'd go again
