Will GM 200r4 work with factory floor shift location?

I found a very cool series of eye-candy pictures for a crossmember/ transmission mount going on over at Hotchkis. Even though its for a manual trans, it's a great concept.

Those guys do some amazing work! Imagine if only the small cut like Treblig made on the driver's side left the rest of the factory crossmember intact. Also, I plan on welding in a concave plate to fill the cut made on the driver's side and add some strength back to the factory crossmember. This style tubular style reinforcement was added to strengthen the factory crossmember and provide the rear trans mount.

After seeing this, my vision is to make new u-shaped brackets welded to the ends of the tube, so it can fit over the remaining crossmember like the original bolt on crossmember/ trans mount does. I'll relocate the driver's side mounting bolt holes over a bit, and have it bolt on like the stock crossmember. The passenger side should remain untouched and use the factory bolt holes.

Enjoy the pics!

Good news bad news.............

I measured my overall trans length today to double check the dimensions given earlier by JBC. As it turns out the chart JBC posted wasn't as accurate as it should have been (no fault on JBC). PATC shows a very different overall length, that's why my measurement didn't seem correct. I measured my tranny length today and found that it was 27 3/4" from the front of the adapter plate to the rear seal. At the PATC site:

http://www.transmissioncenter.net/TransmissiomMeasurements.htm

it shows that the 2004R is actually 27 11/16" from bell to tail. That makes more sense because when I measured mine today (again), it came out to 27 3/4 from the front of the adapter plate to the tranny seal. 27 3/4" minus the 1/4" adapter comes to 27 1/2" which is close to 27 11/16". But unfortunately for JBC, it will require more cutting of the driver's side and the extra cutting on the passenger's side. JBC wrote that his tranny (and adapter) was 28 3/8" which is longer than a standard 2004R with the TCI adapter attached. Mine measured 27 3/4", so with the REID adapter bell housing and plate (ring) JBC will have to cut more than I had to cut. Maybe as much as 1/4" or more. The driver's side cross member will have to be completely removed in the area that I had previously pointed out. The passenger's will have to be cut about 1/8" to 3/16" for the 2004R housing to clear in addition to removing the ear (mounting lug).
Now understand that I am making assumptions. Hopefully JBC will not have to cut more than I did but it does explain why he had to send the converter back to the manufacturer.
QOUTE FROM JBC's PREVIOUS POST,
"No, both the pads and the ring gear are 5/8" too deep into the transmission right now. It's actually in 3/4" with the converter all the way in against the pump with the transmission standing on the tailshaft (dropped it in and rotated it until I got the three clunks), but I have to take away 1/8 to 3/16" to allow the recommended freeplay.

Somebody tell me I'm wrong....please!!!
