Welcome JJ,
You told us the tranny was a GM T56 but is it the GM (011) Aftermarket version or removed from a GM? This is an important ? as the aftermarket 011 tranny has many user friendly options like a mechanical speedo, different ratios, no auto up-shift and modified adapter plate to allow scatter shield install etc... Also check for a 15 degree rotation as mounted.
The GM and aftermarket tranny allow the shifter to be rotated and moved about 3 inches on center but I think you want to move to the modified position. Check out this web site as between 3 inch gain on shifter and offset lever you may be able to save a ton of time and $$.

I also push the outboard push slave from Compton instead of the internal HYD. throw out bearing. Pulling everything for a leak stinks !!! not to mention needing replacement disc and maybe Pressure plate if oiled down. Use a 1 inch bore and a 3/4 " Master Cyl. for great pedal feel. This is what I run in my personal car and a nice set-up for sure.
