No! That's not wear in the housing!
Someone at Longbridge finally noticed that the housing was incorrect; the bearings should be laterally held and the outer lightly held. They arranged one end to be machined out to allow the outer to find it's own centre. This is dealt with on P168 of the green companion book (750MC publication) in an article by Jack French, written in 1952.
MJ1 - 3/4" wide
LJ7/8 - 9/16" wide.
Not sure about the spacer, can't find one at the moment.
Have you compared the old and new pinions on the bench, side by side??
