Got home and checked. One of the covers still had that cage in it. It is a Torrington y-1812 needle bearing. I used calipers on the ones I removed and all measure the same in every dimension. 1812 is a standard size and just like the two other needle bearings int he case and the two replacements in the kit. I ordered another one from the net and will try pressing it into the cover. and compare the two once done.
