Thanks for the replies, I have a total of 42" from side to side with a 4 1/2" high driveline tunnel 8" wide. You can see I only have 21" total for each seat if they set 4 or 5 inches above the floor. I have 25" from floor to top of rear deck, would like not to have seat backs above that. That's why I think mg or like seats are what I need. This is a hand built doorless roadster on a 61 chevy frame, body is only 12 1/2 feet long, hence fairly small car.
