Bob,

Broadcast Sheet Axle Code 015

ALLEGEDLY, Code 015, at least as far as info I have seen to this point, indicates that for 71 E-Body with 3.23 standard axle, with 11" rear brakes and 7260 u-joints (both of which I have) shows the spec requires the 1-7/8" 489 diff. Sorry to disappoint any previously published info!!! Also, the date codes on the gearset are dead on for my car, and the diff assembly date (2/9/71) AND the ratio (3.23) are STAMPED DIRECTLY INTO THE DIFF CASE. No tag under and mounting nut.

I will also state without question that my car was 100 % untouched prior to my acquisition, as verified by conversation with the original owner, as well as my observations during disassembly.
