Swap Mustang T56 Input Shaft for LS Recently obtained a TUET-1259 (2.97 first) T56 out of a Mustang not realizing it had major differences compared to a GM/LS application. Trying to salvage the situation, I was wondering if simply swapping the input shaft for an LS 26 spline input shaft would suffice for my application. I thought I read somewhere it would not work due to gearing, but I am not certain. I am aware I need a mid/front plate and bell housing for GM/LS applications.
We are trying to swap a LSx/T56 set up into a 1969 Corvette. Ignoring shifter placement for now, I am assuming I can possibly get a 31 spline yoke and put it on whatever drive shaft I need to compensate for the different main shaft. When and if shifter location change is needed, would it be as simple as swapping tail housings?

I'm pretty sure you can get a Ford 26 splined input shaft, but you will need to have the input shaft bearing diameter turned down to GM's diameter, 0.590", I think thats the correct number.

I read about the synchro different, but does the input shaft affect that?
That's what I was thinking. I just don't know if the "internal" gear on the input shaft has a different tooth count or "fine/course" difference. So maybe just a 26 spline mustang input shaft, LS front/mid plate, LS bell housing, and input shaft bearing? Would simply swapping the bearing do?

Actually that is not correct. There is an LS length input shaft with 29 teeth on it that uses a 1 piece synchronizer ring.
