Correct rear axle for 1970 Camaro L78

[Jeff H]

The COO would be correct for the 4.10 posi. My L78 came with the 3.55 posi originally but right now it has a COS housing with the original 3.55 posi setup in it. So I'm also trying to locate an origina COX rear but I need one dated 3rd week of Jan 70 or earlier which will be real tough to find. Someone on the 2nd gen board listed above had a COX rear and I think he told me it was a March rear. I'll forward his contact information when I get home from work.
