Transmission Swap and other things

The widths vary between brands.  Just make sure that there is no groove worn on to the sealing area of the crankshaft.  The seal does not have to be worn out to cause a wear groove.  I just did a repair sleeve on a rear end pinion shaft.  Big wide wear groove, not the typical thin seal spring wear.
