@diesel911 - thanks a lot, really helped me
I was looking at timken catalogs, and apparently they dont make a metric seal in 45x64x12 - the other bit is that the 95 E300D uses a set17 and set2 wheel bearings assembly which is not used by other 124 diesels
the autozone seal does not make sense to me, its like the diff seal of an old Honda manual tranny - the dimensions are way too big
