T56 in chevelle

[rusty]

I have a 67 chevelle with a small block and would like to put a T56 out of a 99 camaro in it. The car is currently a four speed with a bench seat. I would like to keep the bench. Do I need to move the shifter to the forward spot or can I just use a different shifter that moves the handle forward without tearing into the transmission? I would also like to keep my bellhousing and clutch how well do the adapters work?
