SFK will not sell you 1 or 2.I had to purchase 10,000 and they were stamped with my part #.

I got my last ones from good griend and oso member Dock Holiday! his were made by AMI and part#UG207-22. i used a fafnir bearing b4 too. it does has a little different look as one side of the center is longer but i turned it in and it worked fine. part #G1106KRRB+COL. +col stands for collar, it comes in the box but i imagine you can order w/out it. Hope this helps!

If you have not put it back in here is a trick I used. I found a long piece of round stock that fit in the inner race and inside the spline located on the flywheel. I therefore had alignment with respect to the gimbel housing. I found a piece of black pipe longer than the protruding round centered within the spline. I then found a pipe bell reducer that would thread on to the black pipe and whose bell diameter was small enough to loosely fit inside the gimbel housing and face up with the outer race of the bearing. One whack with a small sledge and it was in and seated. I did face the bell on my lathe to properly meet the bearing. I still have the rig and will rent it to you for a case of beer. I know you have your engine out and you will need to have it in and aligned to make this work.
