Hey guys I installed a 04 Cobra IRS in my Mach1 last February. At the time of the swap we changed pinion flanges so he could keep his alluminum driveshaft. Now I bought a alluminum driveshaft from a 04 Cobra and a new pinion flange because I was going to put a T56 in it. Well I git ripped off on the T56 (long story) so I want to use the drive shaft with my T3650 tranny. Does anybody know what ujoint I will need to connect my stock tranny yoke to the 04 Cobra driveshaft? It could possibly be the same ujoint and different yokes, I don't know. Thanks
