OK, I found them in two catalogs and it's kind of interesting. I learned something. The Chevy 216 from '37-53, the early 235 '49-'54 (not the full pressure 235) & all the GMCs 228-302use the same cam bearings. The 235 & 261 from '54-'62 use a different set because the cam had larger journals.

I found this from both a Perfect Circle & Dura-Bond. PC # SH209S DB # CH-2

I wish you were closer. We will be touring the Dura-Bond plant in Carson City after our Chapter meeting next month. The guy who runs it is a member. Dura-Bond makes almost all of the cam bearings used in the US no matter what label is on the box they come in. It is an interesting process. I'll see if I can take some pictures.
