    Well...after one heckuva day yesterday for my first time wheelin, I find myself in need of a new yolk for my rear driveshaft. :) It's a stock K5 with a np205 and 12 bolt rear. What year models will have the same front yolk that i can get another one from, and a spare for next time?

    Good luck on a yoke... every junkyard for miles around me is tapped out of these parts.. I finally had to buy a new one from Driveline Specialists here in Cincy.. for $42.00.... ouch, but not TOO bad..


    Get yer wallet out, you will find this hobby is a money pit, but worth it.

    It is hard to say what slip yokes fit what, so many people have swapped componants and such. You need to count the splines, and measure the yoke and start hunting... Definately take the broken one with you when you hit the yards...

    Look for 12 bolt trucks from 70's and early 80's . There is a difference from automatic 1310 u joint , and 4 speed trucks 1350 u-joint . I have one of both , but they are tied up being used . Check out the for sale forum , maybe someone has one or can score one in a yard in their state if you can't find one :k5: :k5:

    4 speed trucks with 12 bolts still use the 1310. Only 4 speed trucks from 81-up with 10 bolts have 1350 driveshafts. (and of course 3/4 and 1 tons regardless of tranny choice).

    Trucks with 4 speeds in the 80's often came with 1350 rear driveshaft. Automatics came with driveshafts with S44 joints which are roughly 1330 size.

    Thanks for all the great input. :) She drives fine without it, but a front wheel drive blazer just doesn't seem right. :D I'm gonna hit the yards i can find around here in a bit that might have one, and if not, $50 for a new one ain't that bad, beats the heck outa having to replace that 12 bolt.

    Well I don't know where 77chevk10 got it , but the 12 bolt I bought from him has a 1350 yoke on it , and the driveshaft from the 4 speed truck fits it :D

    The yoke on your 12 bolt it stock. Andrew's truck was originally a 4 speed truck so the axle had a 1350 yoke from the factory.

    LOL, you know why I made the post I did, about never knowing for sure what you got till you measure it.... take your yoke, and go shopping... good luck at the bone yards, buy a few if you find'em
