A855 - 5 Speed

The Tremec T56 Magnum swap has been done enough times now -> just forget about ever returning the car to stock (you're not going to anyway), do the ToddRon crossmember and the T56 Magnum, proven stuff, liberty can face plate it, whatever you think you need. It's even the Chevy LS transmission so these will be around forever. Once you get the crossmember in and the floor figured out, the rest is frankly very easy.
I won't be returning to stock, and I would be willing to cut the original 4 speed hump out (and stash it away with everything else original) however I'd have to get rid of the bench seat.
I like my bench seat, it's amazingly comfortable and I like the look, I didn't even know a bench seat was a thing in a 67-69 Barracuda before I saw mine for sale.
I'm a little attached to it, and the 4 speed doesn't bother me on the highway, but a 5 or 6 speed would make it 'complete' in my mind (that and power windows, ha!).

Got the efi, swaybars and junk already, maybe, some day, I'll ditch the bench for some modern seats and a 5+ speed.
Is there a list I need to be on somewhere?
