Best shift option for early a with bench???

Ive just ran into a perplexing situation as i'm on my way to installing my 360/904 into my 63 Valiant. I gathered all the parts for the column shift but the real problem now is that im using 360 magnum manifolds and the down pipe runs exactly where it mounts from the transmission to the frame. What options do i have in this case? I thought using the early a drivers manifold but that would really choke it out, TTI's would be an option but they wont work with column either. What aftermarket shifter would work or be my option with a bench? Any real world experience would be greatly appreciated.

Thanks.
