Will GM 200r4 work with factory floor shift location?

After sleeping on it I decided to cut the hole at one of the bottom corners (will post pics) get it all cleaned up real nice an take it to my radiator man who can solder and seal in place (silver solder). He doesn't charge very much for a quick solder job especially if you prep it in advance. Should cost about $20 Max. A professional welder would charge $50-$60 just to turn their welder "on" and that's no joke!!!
Later I'll today post some more pics of the inspection pan that I massaged a little more. Then I'll address a problem I hadn't even thought about...neutral safety and reverse lights. Turns out Mopar put all this on a switch on the tranny and GM puts it on a mechanism on the shifter. Fun, fun, fun on Sunday!!!
