NAPA usually sells good stuff.
What do you mean "broke"? I think you need to look at that U-joint and figure out why it "broke". Overtightened the straps??
By chance by side-stepping the clutch at 5,000 RPM?

What tire size, gears and motor and trans set up and lift size?? All that matters you know
Get a Dana Spicer gold series $$ but worth it.
GOLD SEAL Universal Joint,1350 Series Driveshaft Ujoint
Are you putting some lock tight on the hardware and lock washers on the clamps?
And you putting the correct width and diameter u joint in there in the first place?
Are you caps fully seated in the flange, under load or heavy excess go pedal release take offs are your rear springs "S" flexin and giving you a real bad pinion angle and blowing the u joint?

I got in a hurry once with the u-bolts with out enough light to see what i was doing. Never got the caps seated right and just as soon as i put it in gear , i heard the drive shaft beating on the shop floor. Cost me another new joint.

If you're talking about the driveshaft u-joint at the t-case, check to make sure your drive shaft is "in phase". Mine wasn't last year and POP, shaking, pull over, yoke ear at the u-joint broke off. Wasn't in phase.

Are you breaking the u joint caps or burning up the splines in the cap? Yes you should always torque IAW the manual.
460 and 35's.....yea its getting worked if you are hammering on it all the time. Is this a new symptom or has it always done it? Did it start after you changed something?
Are you trans and xfer case mounts/bushings good and tight? Motor mounts good?

Are you getting u-joints with a grease zert that you have to install, or sealed ones? Sealed ones are suppose to be stronger that the ones with the internal grease channel.....
The welded look is a strong indication of NO lube or cheap u joints that has failed. Once you hard slip the clutch and damage the cap splines (needle bearings) and they quit rolling smoothly its only a matter of time.
Over torquing the caps can cause damage, correct torque and lube is a good thing.
Tight ck at the attachment hdwr and CAREFULLY use a pry bar to see if the trans mount is broken. Do you understand that statement?
