Will GM 200r4 work with factory floor shift location?

I picked up the recommended radiator fittings today along with a 25 foot roll of 5/16" tube and fittings. I got 4 sets of radiator to transmission cooler lines, so I can practice drilling, tapping and soldering. Thanks for the guidance on this Treblig!

OK, tonight after work, I drilled out the back side of the 5/16" female to 1/4" male fittings that would normally bolt right into a GM or Ford radiator cooler. I used a 5/16" drill and an 1/8" NPT tap. I stopped about 1/4" from drilling all the way through to the female flare. I also deburred the bigger hole with a larger drill by hand.

I then cleaned the parts with brake cleaner and blew them off good with compressed air. I screwed the 1/8" double sided male fitting that fits the Mopar transmission cooler, and silver soldered it with the real old fashioned quality silver solder.

The Treblig adapters and the factory 5/16" transmission fittings were all drilled out to the next drill size up in my drill index 15/64" or .234". They were all originally .220". This increased the inside diameter slightly, but didn't seem to affect the flares inside the fittings. I 'm confident the 5/16" flare nuts that I will put on the cooler lines will seal like normal, and I will get a bit of extra flow.

I include a picture that shows what the fittings currently look like in my car with the 5/16" lines and the stock Mopar 1/8" radiator cooler fittings.
