I bought a Stag J-Type box a while back intending to convert it but I haven't done it yet. Curious what the group has to say.

They added needle bearings in place of the brass thrust washers at each end and an additional bearing  in the lay gear at the end where 1st gear is. Has anybody tried this set up in a racing box? Does it help in the wearing of the layshaft?

Don't at this time plan to put another bearing inside the lay gear. If I make the lay gear deeper inside, I am afraid it will not be hard enough for the bearings to ride inside.
