A couple of notes. First, the fab work looks great.
Second, the thru the dash cages are wonderful but they can create a real headache if you roll. The legs get tweaked and can make a mess of the dash. They're also a gigantic pain in the *** to remove.
I've two big rolls on that style cage. One was 360* and the second was 720* plus. That cage was cut out after the second roll and remade from scratch. The replacement withstood more than a dozen flops onto one side or the other. I didnt do another full roll.
