I just bought one for my 700R4 swap.

Hope this helps.

I went with the B&M deep pan. Came with a drain plug and temperature port.

I would skip the tube style pan out of metal in the rust belt . . . . winter time would eat it up ! ! !

get a cast aluminum pan for the extra capacity and it also helps stiffen the case.
