Any info appreciated on shortening the output shaft or does someone sell an already modified shaft? I have the 27% OD trans. Like to put it in my 30 Tudor.

Thanks, j
I am in the process of installing a T170 in one of my A's currently. I'm doing all the machine work/fabrication myself and documenting the process. Also, this trans will have the "Goldilocks" ratio mentioned on the Fordgarage website. This trans will have 3.01 first and 27.0% OD vs 3.25 first and 27.6%OD for the stock RTS trans. I'll probably have an extra output shaft or whole transmission (or 2) for sale, when done but not kits. Currently working on the trans outputshaft/torque tube interface. Once I get my numbers figured out I cut/re-spline the output shaft and while I have the mill set up I'll do at least a second and maybe a third shaft while I'm at it.
I did have a little bit of a setback (literally yesterday). I pulled the torque tube, driveshaft, and pinion, and well, see the pictures. I wasn't expecting to have to rebuild the rear end. It wasn't making any noise so I only expected to have to shorten the driveshaft.
For those wondering it is possible to create the "Goldilocks" ratio (I'll be documenting how) but I think I have the only 2 gearsets, on the planet Earth, to do it. ☺
