BUT another part of the processes in the Chaffin book is measuring the amount of clearance between the bearing and the plate, once mounted. I could take the outer SHOULDER of the bearing and press it into the plate. Not good as it would have worn the plate pretty quickly of course. One side of the inner race was a bit scored, and it looked to me that the side force would/did push the balls into the scored side. $100 bucks for a new one. So, welcome to the slippery slope called Ruckstell.
I saw on the MFTCA forum people taking about measurements of the bearing, etc., but not the part number used. I browsed the various vendor catalogs trying to find the best price, and noticed on one of the images the blurry outline of a part number on the image. Click to Enlarge it said. I did, and thank you very much there was the part number. At this point, eBay was my friend by many dollars.
The bearing arrived, and installed it as shown below. As you can see I put some Locktite bearing locker on the shoulder as well. Note that, again according to the book, the thrust plate was used as a backer to keep the bronze plate from deflecting during installation.
