SBM 340 Rear Main Cap

Place an ad in the parts wanted section. 340 main cap appear on and off.
Good luck
I have a 340 block with no mains. I was hoping I could use 318s. My machine shop just informed me the rear main is too short.
Nobody makes one. Anybody have any suggestions? At least, any help on specs and dimensions to have one made?

First post, have mercy, thanks
Exactly, start a wanted ad if you are looking or look through the sale ads. Just because an ad is old enough to be closed doesn't mean the parts have been sold. Like this one, contact the seller through a personal message and he may still have the parts you need.
