Title: Driveshaft Length
Post by: williebm3 on April 06, 2016, 07:46:07 pm

Looking for a Ujoint to Ujoint measurement for stock rear driveshaft on 81 K20 with a 400/208/14 bolt FF combo? Mine is short once I got truck together and looks like PO did not have stock driveshaft.
Thanks in advance.

you should do the measurments yourself - center to center at the yolks.

I realize that. I am trying to get an idea on what it is supposed to be.

something im not sure if the 208 came with a slip yoke or bolt on or could it have either. but that combo is pretty common all military trucks should have it unless they are a dully or blazer. im sure blazen has it also if he didnt lift his truck any
