Hi
I am replacing a blown 1978 NA engine with a 79... same type. I was attempting to replace the clutch pilot / needle bearing when it disintegrated. Since the sleeve is in bad shape, I'm getting a new sleeve & bearing combination.
My problem is this: The old engine had a brass bushing as a bearing, which was badly worn. The replacement engine had a stock bearing. The torque tube shaft is 12.7 mm but the new bearing ID is 15mm.
Does the shaft go really far into the back of the engine or does the pilot bearing ride on part of the splines for the clutch?
I dont want to assemble a new bearing/sleeve combination only to have it fail.

I would like to post some pictures, but this is my first post, and I haven't advanced that far yet 😳

Any help is appreciated
Thanks

I did this recently, yes the input shaft does go that far in

If I recall correctly the pilot bearing is the same as a Mustang II available at any parts store.
