Yet ANOTHER Hemi swap, but need input

A727 and A904 transmissions work with your existing trans crossmember unmodified. The US car tool cross member setup is for a Mopar overdrive trans A500 42RH or A518 46RH.

I thought the 904 required a diff cross member. But if it does NOT, well that means this is getting better and better!
