    Please give me suggestions for a driveshaft donor vehicle. I need a decent amount of slip spline with a 1350 yoke at each end.

    OK, so nobody had any suggestions. I couldn't come up with a vehicle that took something like this, either. I spent hours in junkyards looking at hundreds of driveshafts and finally found something that will work. It is half of a two-piece shaft from a 91 3/4-ton Suburban. Everything is 1350 series. I took the section with the slip splines in it, which is about 24.5" in the center of range of motion. I was looking for something 1/2-3/4" longer, but this will work short term with the seal on the splines removed. Then I will have it lengthened at a driveshaft shop.

    This is for my Blazer with 14-bolt rear and slip-yoke eliminated NP208. Static length for this application is 35.25", in case anyone cares. (Stock driveshaft length is 29")

    Find a 3/4 ton fixed yoke truck with a 1 piece driveshaft.

    Yeah, roll your eyes at me, but that's where mine came from.

    Of course. It's just that what I really needed was make/model/year of some trucks that were 1-ton with fixed output.

    The K5 wheelbase is different from anything 1-ton, so I didn't think I would find a direct bolt-in shaft, but I was looking for a good core that would just need to be retubed/balanced. As it turns out, it was very hard to find for some reason. Also, you can't call junkyards or do web searches for "drive shaft with slip splines and 1350 U-joints". You need make/model/approximate year or you have to hit every yard by foot and search them all over. Around here, there is almost nothing 1-ton in yards.

    Anyway, I found the motherlode of junkyards. 6 big yards all within about 2 miles of each other and within 45 minutes of my house. 4 of them had a semi trailer full of driveshafts. Even with that, it took me 4 hours to find a good core.
