Butchered 72 swinger

Recently bought 72 swinger and did not realize the extent of damage the last idiot that owned it did. Has cut pulled twisted the trans support and body hump so a 4 speed from a b body would fit, rather than making a bracket and moving shifter he butchered the hump. So I have new trans support for both auto,4 speed, but I have a good deal in the works on a fresh 727,t converter,and b and shifter. Do you guys think this would be the way to go or fix what I got with the b/e 4 speed. Not sure what to do with my new 8000 dollar lawn ornament at the moment.
