This oil pan came off of a 72 400 block. The kid I bought it from banged up one part of it as can be seen in the pictures. The oil pan has had oil in it but the engine was never run. The pick up that fit this block is the one with the small threads. (Far left in the pic showing the threads) I have no idea what the other two picks ups fit and they are brand new. Make me an offer on whatever you want. I have no need for any of these. You pay shipping. Thanks!
