NP205 front output yoke bolts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

jobrla · 03-31-2015, 06:32 PM

Well, I seemed to have had another senior moment. After rebuilding my NP205 and my front axle and yokes. I can no longer find the 4 yoke-to-yoke bolts that holds them together. In all my research, no one seems to have these in stock or give me measurements. The closest I have come up with is..

Thread .312-24
Thread length 1.43" (1 7/16)

Any thoughts

Here is a pic of the yoke on the transfer case and axle

Okay, I have made a positive I.D that they are in fact 5/16 fine grade 8 bolts. Just now need to find the length

I can measure one tomorrow

I have some 1-1/2" long

Cut them down if you have to...

I tried a 1 1/2 bolt but will not let you line up straight to start. Head of bolt touches transfer case collar. Can't cut a grade 8 bolt.

Looks to be close to 1 3/8 maybe the 1 7/16 from your first post is correct.

You could probably run a nut on and grind the end down to the correct length and then back the nut off to clean the threads up.
