[TR] Does a TR-4 differential and axle fit a TR3A?

[Geo Hahn]

Terry -

The failed seal may just be the one inside the axle, not the one in the
hub.  If so, it is not a big job to pull out the axle (hub still attached)
and replace that seal.

I am thinking a TR4 rear will be a bit wider than a TR3.
