    I REPLACED MY STOCK TRANS & CASE IN MY 86. THE TH-350 & 205 ARE SHORTER THAN THE ORIGINALS. I'M HOPING TO FIND A TRUCK THAT RUNS THE SAME AXLE WITH THE SAME DISTANCE FROM CASE TO REAR.I KNOW I CAN HAVE THE STOCK SHAFT LENGTHENED, BUT I NO LONGER HAVE IT. I WANT MY" PARKING LOT PROJECT" TO REMAIN EASY & CHEAP. THANKS IN ADVANCE.

    Get a Short wheel base p/u or Long wheel base pickup shaft and have it shortened. I hear shortening is less expensive than lengthening.

    Yep, to shorten it they just cut off one end, cut off some tubing, then weld the end back on. To make it longer they have to cut off both ends and weld in a new piece of tubing that's the right length. More labor, plus the cost of the new tubing to make it longer.

    I think that the 350/205 combo was pretty rare in 2nd gen K5's. I don't know if a driveshaft from a 1st gen K5 with that combo would be the right length or not.

    I just did the same thing to my 82. With a 4 inch lift, slip joint 205, and a 14 bolt the main shaft needs to be 36 inches plus the slipjoint. I'm not sure about the front yet, but the front drive line out of any TH350/205 should work.

    you could just find a blazer in a yard with the same set-up,,,i think the rear shaft for your's need to be 31 inches,,the other shaft for the 700r4 was 29 1/2 inches,,,check out a local yard,,they will prob. sell you one pretty cheap,$25 or $35,,good luck
