What Terry said.

LJ35G = SKF6207A I believe.
MJ1 at rear

There's also the little roller race on the input shaft but as far as I know they aren't obtainable.
1.875" x 0.46" x 1.125"

The roller bearing is replaced by an inter bush for 4spd box from A7 suppliers. Terry.

Didn't mean that one Terry (though you are right to add it) - the one on the front end of the 1st motion shaft.

Thank you for this -  I thought the input bearing I had listed seemed wrong.
