drive shaft length

[ITSARAT]

Can someone please tell me the length of the rear drive shaft in a 87 short bed 700r4 - 208 case, from center of u-joint cap to center of cap.mine measures 40 1/2 inches. I think maybe my truck has a drive shaft out of a K5 Blazer because it seems to be short. It has a 6 inch lift and I think I only have about 4 inches of the slip yoke on the splines in the transfer case.

Heading out to the Resort later on today. Will get the measurement for you.

Just measured my own (stock height 83 SWB K10, 700R4, NP-208 with 3/4 ton SF 9 1/2" ring gear 14 bolt rear). The stock shaft is right at 40 1/2" center-to-center on the u-joints.

After adding the 9 1/2" rear end and when fully loaded that drive shaft is dangerously close to ramming into the NP-208. If I had the luxury of time and money I'd have it shortened 3/4" at the local machine shop.

If you haven't already done do, I'd loosen the rear u-joint and slide it forward to check clearance. I suspect that you may be OK.
