I have a 10 bolt rear end in my 68 rs and would like to know more about it. Is it 8.2 or 8.5 Here are numbers I took from it. Drive shaft side. con1 is on the left side fasing it from the front. these numbers are on the right side 889485nf. I would like to put in a locker and want to know weather its a 8.2 or a 8.5  I believe that it is the origanal rear end any help would be appreciated.

You're missing a number. It should be 3894859 which is a 1967-1969 Camaro 10 bolt or a (late) 1965-1971 Nova 10 bolt, both being 8.2". Check the date on the other side to narrow it down, and also check the passenger side axle tube to see what ratio it originally came with.

L157 is the casting date (December 15th, 1967), and yes, it's a 28 spline. If your car was assembled in late December, 1967 or early January, 1968, it's probably the original axle.
