Will GM 200r4 work with factory floor shift location?

I took the tranny pan to the radiator man and to my surprise he said he could do it while I waited. He only charged $20 to braze it but be aware!! The pan is coated with something (maybe aluminized). Either way the radiator guy had a hard time getting anything to stick to it so we had to sand (lightly grind) off the outer layer. All the time I've had this old (1987) 2004r I wondered why the tranny pan didn't have any rust on it considering it wasn't painted, now I know why. You can see the angle that I held the drain plug so that I had maximum ground clearance and (looking from the inside) also be able to drain 99 percent of the trans fluid.
PS - If you do this yourself you might make the hole in the pan just a hair small. If you make it the whole 1/2" it will come out a little big because you drilling in a corner radius. So if you make the hole a little small you can use a rat tail file or a dremel (die grinder) to make the plug fit perfect and at the proper angle which makes it easier for the radiator man to fill the gaps.
