Driveshaft Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

stateamind · 10-22-2003, 12:48 PM

Ok, so I have a 700r4 from a 92 1500 donor installed in my 71 c-10 shorty. Plan on using the driveshaft from the 92. I like the idea of bigger u-joints. I will have to get a couple inches cut out of it, but that's ok. My question revolves around the pinion yoke. I've seen them somewhere online before, but can't seem to find them again. I need one to match up with the bigger rear joint of the driveshaft. My 71 is smaller. Anyone know where I can find these? Or possibly an easier (cheaper?) way to get the 700r4 connected to the 71 rear? Thanks guys.

I think they are called Hybrid U-joints and can be bought at NAPA. I used one to mate a 3/4 ton 4x4 driveshaft to a 1/2 ton rear pinoin yolk

What CPNE said....go to NAPA or a driveline shop and they should be able to get you a conversion joint

I want to do the exact same thing. 700r4 in a 71 SWB .. is it a one pice drive shaft from the 92? How does it fit (lenght)?

Trust me here. I've done this. Two options.

1) Driveshaft from an early to mid 80's shortbed V8 truck with factory overdrive tranny. Straight in swap as long as your engine is in the proper V8 position. I used one from an 83 short bed 305/ 700 R4 truck. Bolts in....

2) driveshaft from a 67-72 short bed 3 speed 6 cylinder truck. Again bolts in.

9 out of 10 people here do not know, but stock 67-72 short bed 6 cylinder 3 speed trucks came factory with 1 piece driveshafts. They work perfectly for this swap. I've done it twice.

Thanks for the great answers to my question guys.

mcmlxix - yes, 1-piece from the 92 ... looks like it's abt 2 inches too long, also has 1330 series u-joints, original had 1310 series.
