some have good luck using the 7260 joint/yoke combo, while others go to the big guy 1350 size.
any idea where the sizes fit in with hp/tq in say, the average B body ? assuming a good yoke and solid joint ?
Difficult to say because there's a lot more to it - weight, traction, torque, stick/auto, etc. Same situation with how well an 8 3/4 will hold up. (ring & pinion and caps). A heavier, dead-hooking, higher HP/torque combo will eventually find the weak link in the "chain" - output shaft, slip spline yoke, u-joints, driveshaft tube, rear end yoke, gears, caps, axles, wheel studs. My Dart at 3,540 + lbs pulls the wheels every run. Early on I found out the hard way that an OEM yoke can eventually spread, gets hammered from the movements & breaks, or just plain fatigue.
