small block Chrome oil pan

I have a chrome oil pan for a small block. I was going to use it and had it in place and it didnt fit. The gaskets were fine except the rear oil seal. Its smaller in length then the front. I have a 73 318 and all was well until the rear seal. No oil has been in it. I measured with tape....From top to top in front was 9 1/2 inches and rear was 7 1/2 inches. Its approx. the same weight as stock and the lips seem heavy as well.I would use it but it wont work. I would like to pass this on to someone were the application works. No markings on it stating anything. I got this in a trade deal. Im lssing but OH well. I would like $25 plus shipping.Im trying to be as honest as i can.If your interested great..PLEASE make sure it will work...Nite Moves
