With the dash and all the interior out of the car I would suggest you put a cage in the car, not just a roll bar. Then you could have more options.
Looks like a good excuse to buy a bender. I am sure you can find other parts to make with it.
I agree that a CM cage should be installed from the start."J" bars and a mid plate too.That way it's DONE and the next caretaker can go right to 8.5 with it.
I saw a car with the truck directional switch and I didn't like it.Might consider a stock column gutted like Doug.
