Buy a race seat that is made to fit you like the sparco EVO 1,2, and 3 they go from small to large. Make a roll cage and beef the ---- out of it. Oh lots of padding too. that should keep you safe and stuck in the seat. that is the only way I would build one.

You don't need to use an automatic, you just need to rig the shift linkage... It would work from the front, think about the motions, they dont change regardless of if the tranny is in front or in back of you... (if my brain is working right, picture me making shift motions)
