Best I can read,with a magnifying glass is 3B OR BCDA 465XXX. SEARCHED ALL THE INFORMATION I COULD FIND BUT NO REFERENCE TO THESE. I need to replace soon push rods. The ones I got are thicker then the ones I have but the length. Any help would be appreciated. | | | | | Joined: Mar 2004 Posts: 6,212 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,212 | Did you flip the prefix letters...BCDA? BDCA is a 1946 1/2 ton truck engine built in the Flint engine plant with RPO-227 (HD Clutch for HD 3 & 4-speed transmissions). I don't know what 3B OR is??? Post a picture...

The replacements I got are the correct length but are about .315 wide. Checked a couple of places and all they have are the wider ones. Will they work? | | |
