Stock Style Oil Pans, Which Ones Best?

I bought the hemi pan from 440Source, very thick steel. Unfortunately, my steering did not clear the corner of the notch and I needed to persuade it with a sledge hammer. I'm running a direct connection 73+ A body big block spool k member with B/C body factory spool mounts and 73+ steering and there was about an 1/8" interference. Once the corner was massaged, the rest of the notch gave it enough room.
