Does anyone have a good source for a listing of rear end codes for big cars from 1960 thru 1965. The build sheet on my '64 Grand Prix says "WH" in the axle box, and I haven't had a chance to look at the actual stamping on the rear end.

Thanks, Paul

But... if the hog's head has been changed the axle color may not tell the whole story. You'll have to see the raised # on there to know what you have for sure.

Where is this stamp located? My shop manual says it's on a little flat surface on the axle tube to the right of the differential. Mine, naturally, is blank.
Been trying to determine the ratio on my 66 Cat...
