Title: Rear end yolk sizes
Post by: project1 on October 15, 2014, 11:15:23 am

Need some info guys I have a 86 K10 with a 12 bolt rear end missing the yolk. In my area there are a few early model 90's kicking around the scrape yards will these yolks work if they are a 12 bolt. If not what other options do i have?

I ran into this awhile ago mine was worn in the cup area. Only 12 bolt yokes fit. The spline count is different and ten bolt ones have a different u-joint size. Try a tranny shop or aftermarket might be surprised.

Do you have a local driveshaft shop in your area?
