I just pulled out the pinion oil seal on my 64 Alpine and grabbed the replacement only to discover it was much smaller than what I just removed. The old has an inner of 1.5" with an outer of 2.55"(as best I could measure) and a width of .5". The replacement I got from Rock Auto was a National 470625 with the same inner diameter but outer is 2.25" and width of .312".
The original is a much beefier housing, probably the original seal since the rubber was pretty shot.
Does anyone know a cross number for the original sized seal?
