U-Joint Help

[Chipper2oo3]

Recently bought a 83 K10 and am running into problems with parts. Seems the previous owner has swapped parts with a pre-80's truck. First I had to replace the steering gear box and the lines were flared instead of being the later o-ring style, plus the steering coupler was too big for the gear box shaft. Turns out it was a 13/16 rag joint and the 83 box had a 3/4 shaft. Now I went to replace the u-joint on the rear driveshaft (closest to the pinion flange), bought one for a 83 and it went into the driveshaft perfectly, but the caps are too big around to go into the flange for the pinion. ( the flange has a keeper on the ends to hold the joint in, with u-bolts, instead of open on the ends with straps and bolts) Looking closer the rear end is a 12 bolt out of an earlier truck and guessing they used the 10 bolt driveshaft with a combo joint with two different size caps. Anyone ran into this and have a part number?

I know for sure that a conversion joint is available, but beyond that I'm no help.

Wow, is this a steering shaft or drive shaft discussion??

Drive shaft John

Get the precsion book out and look at the measuments for a 12 bolt and the meassurment for your d-shaft and then look at the conversion ujoint page in the back of the book they are easy to find.

Go to Napa and tell them what's going on, they will have the hook-up!
