If you build a T like an old track roadster with a tube frame and a belly pan/step pan you can be 7 ft. tall and have plenty of room.
I've got a TH350 primarily because I had it. I love shifting gears as much as anyone, but I'm lazy and didn't want to figure out a third pedal in that tiny space. Thanks for the compliment on the woodwork. I did cabinetry and furniture for years and wanted to reflect it on the car.
That's awesome! I think you accomplished just that! 350 seems like a good choice. I'm going to try cramming in a third pedal, we'll see.
I'm 6' and 185. I've had a few roadsters and drove the hell out of them. The tightest fit is an RPU. I don't do automatics, so they all have 3 pedals which is a challenge at times. Here are some pics of the last few. Nothing beats a Roadster.
