Jim, if the car has frame connectors, they toss your butt out! Well, no not really, they put you into the modified catagory. There, judging would depend on the workmanship quality and design. At the recent show, they put people who had great looking cars with period correct Cragers, but not original Rally II's into a separate area. So yeah if you're going for awards in the restoration class, this modification, regardless of welded, bolted, or cut into the floor is going to exclude you from the winners circle.
What about swapping to a 12 bolt posi to take the power? Is that as unacceptable as having a Chevy motor? :rolleyes: Golly those are hard to look at.
