'72-up AMC MT Ball Bearing Pilot

Thanks to SKeown, I just got the ball bearing pilot kit for 1972 and up AMC crankshafts to mate to the input shaft on manual transmissions.  Per Steve's instructions, you need to remove the bronze pilot bushing from the center bore in the crank (if present), and the thin torque converter bushing from the large bore in the crank (if present).  Then heat the supplied sleeve, and cool the supplied bearing to get the bearing started in the sleeve.  Next, you drive the sleeve and bearing into the large bore in the '72-up crank as far as it will go.  The bearing will protrude slightly from the end of the crank.  According to Steve, this will leave the entire end of the input shaft supported by the ball bearing, and still leave about .040" space between the bearing the and the splines on the end of the imput shaft.  Pictures of the kit (installation picts will have to wait until I drop my tranny - stay tuned):

The bearing has "NICE" "1630" and "USA" etched into the edge of the outside race, and no other markings anywhere on the steel.  As with so many products these days, the actual manufacturers likely produce for others and put whatever label on the product the contract calls for -- could well be the case here.  I'm sure any bearing with the same dimensions would work.

Thanks so much for that info.  Would you repost the source of the sleeve and bearing?

I've got a gutted B/W T5 as used by AMC sitting on a shelf and could measure the nose of the input shaft on that, too............. I know the bearing retainer is different, won't speak to the input shaft.

But if we can find accurate info, bearings, numbers, that would be handy for folks.
