Help With These 1969 GTO Rear End Numbers Etc
Need some help here...
1969 GTO, auto, 400, had many nice and somewhat uncommon options. This rear end, 8.2, N = Nodular. The rest of the numbers I don't know really. Many years ago, I did a rear gear calculation by spinning wheel and counting mark on DS and came up with 3.55. But this might be incorrect and I noticed... Mark on right axle housing literally says 3.08 L. Above that is T-468. None of the other GTO rear ends I've seen show the actual gear ratio on them. I can't find the HX or HY etc mark on the driver side but I thought it was there at one point. Rear end is gone
