"All" talks about the S-type rearend as the best Jaguar rearend on hotrods, because they don't need to bee shortened.
But they are only 55 inches.
I've seen nice 34 Fords with 57 inch rearaxle.

Is 55 inches too narrow on a 34 if I wish to fill the rearfenders with max wide tires?
Of course, its easy to change the offset on the rims, but that's not a good solution for the wheel bearings.
