T56 Driveshaft?

[cv2065]

Anyone know the correct driveshaft for the T56 coupled with an IRS? Mike Forte says he has an IRS with a short pinion flange so that the T56 has room, but wasn't sure about the driveshaft as FFR doesn't list it as an option. Will the same TKX/TKO DS work?

I believe for a Coyote + T56 + IRS the correct driveshaft is FFR P/N 16038 - 31 SPLINE 2015 IRS 8.375" DRIVESHAFT - For a 427 engine like you have I'm not sure if it is different length. Other options are #60375 (9-3/4" 31 spline) and #60175 (10-1/2" 31 spline). Maybe somebody with your exact setup can chime in.

The engine your using makes a difference too. The tailshaft will be a different distance to the pinion flange because of where different engines sit.

Thanks for the comments all. After a bit of thought, I'll be using the TKX instead.
