    this thing?

    http://www.pirate4x4.com/tech/billavista/PR-1410_Yoke/index.html

    I gotta get new straps for my new-to-me 14 bolt ... but reading this article has me all worried now :crazy:

    What y'all do -- buy them at parts stores, go hog wild like Billavista, or?

    Since I'll hafta get new shafts when I go doubler, I figure I can call Jesse @ HAD and do it all then ... but that's a few months off and I'd kinda like to have a rear axle before then :D

    Get some used straps till you can get a new/modified yoke. Basically, the u-bolt holes are not on the same center line as the strap holes, so you need a mill to correctly modify them.

    I went to Napa and got a set of stock replacment straps and bolts. They work fine for me sofar so I have had no reason to change to anything different.

    Jesse's 1410 u-bolt kit is the greatest.........but Im a tight wad and when he built my d shaft I went with 1350's and bought new straps and bolts at the dealership. DEFINATELY buy them at the dealership as the aftermarkets do not fit well around the cap.

    If you want to go primo spend the $$$ on the u-bolt kit, if not buy the OEM straps and replace them annually.

    :D

    Hey Russ, so you're saying that you can't just drill out the threads and use the U-bolt even though the 1350 and 1410 use the same size caps because the bolt hole centerline in the 1350 Yoke is different than the bolt hole centerline on a 1410? If i have access to a mill can i machine the 1350 Yoke to accept 1410 U-bolts? I know the backside of the Yoke needs to be machined to accept the flat surface of a washer and nut but what else needs to be done, is there enough meat on the 1350 Yoke to properly use the 1410 U-bolts?

    I've READ a couple of articles on pirate where they just grind down the back of the yoke till the bolt and nut fit.I dont know about the 1410 but if you can do it with 1350s I dont see why not.That doesnt sound too expensive to me.As soon as it gets warm i'm gonna try it on mine,I've broke way too many POS straps.I guess it's a bad design and thats why dana didn't use it:D

    Post any results please.

    Yes, the holes are not in the same place for straps and u-bolts. I *think* that in order to use the u-bolts without using a mill to center the holes, you'll need to drill the holes over-size. Not sure if the center line is offset across the yoke too. <hmmm>



    Not sure if there is enough material on the 1350s, I would think so. I think I've still got a 1350 strap yoke out in my shop, and I put a 1350 u-bolt on my son's truck. I'll try to dig it out tomorrow to do some comparisons. If you don't hear from me by 2-3 p.m., send me a PM and remind me...

    I have run straps (from Napa) for three years with zero problems. The conversion joint I'm using is the same age as the straps and still functions perfect, even after losing the front joint on the freeway. I don't worry about mine even after reading that article by Billa Vista, I go by my own experience with a product.

    Milling a 1350 yoke for u bolts will make it weaker than the straps.

    I can get you the correct, GM OE straps/bolts but they're quite expensive from me ($25 shipped)

    I meant front u-joint on the rear driveline...which caused the driveline to fall and hit the ground, breaking the yoke on the front...but the rear u-joint stayed intact, though bound a bit messing up the bolt heads....
