Will GM 200r4 work with factory floor shift location?

These pics show how far back it is from the center of the factory mount to center of the 2004R mount. Very close to 4 3/8" - 4 7/16".
When I measured the distance from the front of the adapter to the tranny seal I got 27 9/16" but that can't be correct so I'll have to measure it again. My 2004R tranny housing plus the adapter should be more like 28 1/2" but I'll check tomorrow and make sure.
Either way the set-up that JBC426 is using measures out at 28 3/8" which about 1/8" shorter than mine is (should be). If all this is correct the adapter ring and Reid bell housing don't seem to save much on cutting the upper cross member. It only makes sense that it couldn't be much shorter because the bell housing has to contain enough space for the GM torque converter to exist.
There's no point in making assumptions so we'll just all have to wait and see. Lucky for JBC, he already knows where and how much he's going to have to cut and basically where the trans mount will be.
I did forget to measure the vertical distance from the factory mount surface to the 2004R mount surface so that if anybody else does try this they'll know where to put the mount horizontally and vertically relative to the factory mount.
