Turbo 383 in a A-body Barracuda

just a question does anyone here have experience mini tubing a fast back and if so how did you work out were the rear seat mounts into the inner wheel house just trying to get some ideas i thought about just narrowing the seat frame but then again someone might have a better way of doing it

The concept is the same on all the cars. I cut out the mounting hardware on mine and moved it over with the Wheel Tub. You can find pics of what I did in my Mini Tub Thread in my link below. I don't know what page but I documented it really good.
