Torque Converter fitment question

LOL Ok... those are both 727. AutoZone can't get anything outside of racing TCs for 904s. Anyway... I unexpectedly got a TC with the latest 904 I bought yesterday. He was a nice mopar fella and he assured me that it would be a functional transmission, and I could just install it for now. Fluid looks good and it doesn't seem to have any leaks, so I'm just going to use the stuff I got, clean my cooler lines and go for it. I'll buy a good TC when I get the 904, in the car currently, rebuilt.

Thanks for the advice folks.
