I having trouble finding the right seal for the center chunk of the rear axle on my 1978 Fiat Spider. This is the seal where the driveshaft enters the "pumpkin" of the rear axle.
The acutal measurements (in mm) are: 68 x 36 x 10 (thickness)

Other numbers as they appear on the inside of the seal are:
100/145146
and
"To 125 FIATGR124A"

Any idea on where I might get this?

I've tried International Auto Parts and a few local import car parts stores in my area, but the seals they have are all too small.
Thanks

Hi, Welcome to the forum.

This is a UK site that supplies oil seals by dimension:

I would assume there are similar suppliers your side of the pond.
