T-56 Swap. Cutt Stock D/S 1.25 or 1.5 inches?

[Jman20427]

Hey guys, going to swap in a T-56 in my 97 Hellion Cobra. Ive ordered the speed cal and trans mount, Ive searched this topic and Ive seen that the stock driveshaft needs to be shortened, however Ive seen 1.5 inches and ive seen 1.25 inches, soooo anyone know for certain which one it is?

I also heard I need to swap yolks out since the T-56(03 cobra) has a 28 spline output shaft and the D/S has a 31 spline?

Contact the FRPP tech line for an exact length.

To use the 28 spline slip yoke, you will need a 1310/1350 hybrid u-joint if you mate it to the stock 97 DS. If you have the FRPP aluminum DS you will need a 1330/1350 hybrid u-joint.
