Hydraulic throwout bearing modifications

It would need to be extra tight on the trans? A sleeve would be able to move both within the bearing and on the collar, which is no bueno. If there was a way to have it from not moving on the collar I don't see why it would not work?

Those Speedway bearings for $80 make me sad, and almost wish i had a GM just to convert it to 4 speed for 1/4 the price all around. Super T10's are almost free in these parts
