Overdrive tranny in an A-body

i've read all the threads i can find here and other sites and it always seems to come back to this








so,
1: no matter what you need to cut the upper support out and redo how you stiffen the floor area
2: using the US Cartool piece just means one less thing to fab
3: in general you want to keep the drive shaft angle as close to factory as possible, even if that means cutting the floor.
4:whether a 500 also needs the floor cut to fit in there is still a question

I can't understand how it's still a question? @MileHighDart just finished his weeks ago and didn't cut the floor. @Junior340 and @TrailBeast been driving theirs for years and they also didn't cut the floor...
