So I bought this from Summit.

It is a spin on oil filter adapter. It doesnt come with a filter. So today I went to AutoZone and while I was getting a filter that fit the threads to the adapter in my picture, the manager stuck his nose in my business and told me that this will not work. He said that there is "no way" this will work because there is no way for oil to come out. I told him originally there was a "containaster" oil filter in my 66. Then he told me "well there has to be a line where oil comes out" (on the canister) and I told him there wasnt. Anyway, now this guy has be askin' you guys. So who has done this and will it work??????? It is supposed to! Here are the pics.
