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.

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.
