I couldn't find those either, but I bought some Clevite 77 CB-1443 P's. On the box it shows an interchange number which is 3755APA. Yes, they are the wider rod bearings. If you don't care about Clevite vs FM, look into these. If you still can't find them and will take the clevites, let me know. I can order you a set at my cost. I'll have to get back to you on the $, I forget...
