Duster 340 oil pan

70duster340 I think your worrying a lil too much I've used 2 mopar replacment pans and they do not have a dimple [at least like your old 1] and they fit fine.
I do understand not wanting to put a motor in twice but I really think it will be a-ok. My 8qt milodon that I run right now has no dimple and there is no steering linkage problems. Even if it hit a lil you could dimple it while in the car bolted up, but I really do believe it will be fine.
I say if it makes you feel better call ron mancini and ask about it.

And mopar makes replacements as well which also fit perfect, I know cause thats what I had before the 8qt.
