I'll just throw this out there.
I have an AOD in my bird and figured out how to run the STOCK floor shift and make it all work.
Looks stock upstairs.
So I don't see why you couldn't figure out the way to mod the column shift also. You could also check with Lokar as they do make a column shifter setup that you could maybe get some parts from? Just don't expect the indicator to line up, of course!
You at least have room to run linkage and such as a tbird does not and is very tight in clearance all around.
You will LOVE the high end.
I actually need to get a new rear gearset as mine is a stock 3.31. Around town it wants to lope too much so I don't use od. On the Hiway 70-75 is 1800-1900rpm. Engine is barely workin! Much more versatile car now.
