I have tried to ascertain which rear end I have on my '81 without success.
The numbers I'v found tells me nothing. they are "62580" and below that is "039534" . Since I bought this car used", the differential could possibly be anything from a 1980 to 1982...right? Because of some speedometer problems, I need to know the exact ratio....anybody hip on this? thanks as always in advance. Jim

PS: i know the serial number is supposed to start w/ OK or OJ to identify the ratio...but I have found only the above numbers.
