Up front we had to run a 1350 yoke on the transfer case for crossmember clearance. A 1410 resides on the axle end. J.E. Reel built us another driveshaft for the front. This one is a little longer but also narrower to clear the TH400 transmission and exhaust. If you think you need big U-joints, Reel recommends running 1350s whenever possible. For the most part 1410 joints are overkill. The 1350 components are less costly and there are far more yoke and shaft options available. But if you still think you need 1410s on your project, J.E. Reel can make it happen.
