See? I didn't have the answer but I knew who did. Thanks stock49!
BobK, Be sure and let us know how this works out. Given the numbers certainly helps sort them out.
I'm not 100% certain, but I may have hit the lottery on my $40 purchase. Attached are photos of the new part and my old end cap (front and back) and a third photo of the other three caps that came with the front end cap. While there is a faint part number on the end cap, two of the others are plainly visible. While I have never seen a babbitt bearing, I don't think that's what these are as they look identical to what is on the current cracked end cap.
