What size are the driveshaft bolts?
Guys,
Real quick trying to help a friend finish a project today and there are no junk yards open/around. Does anyone know the size/thread pitch of the four drivshaft bolts at the u-joint? Hoping they are something we can grab at Lowes and be done!
Thanks!!

They're special bolts. Usually 5/16" bolts with a 5/16" flanged hex head. Try you local auto parts store.
I thought most of the GM u-joints used straps over the caps?

Doh! Ya right. Straps AND bolts. Whenever I think of bolts, I picture solid caps over the u-joint caps held on with bolts or u-straps that go through the yoke and are secured with nuts.
Same things goes. A regular bolt won't work however an allen head bolt "may" work since it's head is smaller than a regular bolt.
It's always best to use the proper parts. Just about every auto parts store should carry a GM strap kit.
