Gentlemen, I stumbled across a craigslist add for a 318 poly. I noticed it had a rear sump oil pan. I would love to get ahold of one of these pans for my curent build. Anybody know what poly 318 cars of that era had this style pan? Or could it possibly a truck pan of some sort. I don't think it's a newer 318 pan, because the dipstick location is different?
