How does the swb k10 rear driveshaft compare to the k5's rear in lenght?

Blazer = 104" wheel base
Short bed C10 = 115" wb
Long bed = 127"

Longer, as you can cypher from the post above.

Is their any other truck or blazer that shares a similiar rear driveshat to our blazers? I need one that is a little longer and I would just have my lengthened but it is all beat up. Would a legthened front driveshaft work? Any ideas let me know. Oh and I have a 72 k5 blazer with 6 inch lift, 12 bolt rear end and np 205 t-case.

When they lengthen a shaft they replace the tube so as long as the caps are good that hold the u joints you should be ok

The ends are the problem. Looks like it wacked something and messed it up.

You might be able to use a 73-87 driveshaft. Longer wheelbase, but it depends on where the back of the T-case is. I had a CV shaft custom made for mine. The original was whacked with 350K miles on it... When I swapped in the 14 bolt, it was too short so I re-drilled the perches to shift the whole axle back about an inch. Nice thing about that is it is now centered in the wheelwell.

Which are you saying has the longer wheelbase, 1st gen or 2nd
