Driveshaft u-joint strap bolt size?

Does anyone know what size/thread the bolts for the rear driveshaft u-joint strap bolts are?

No, i can't just go to the parts store and get new ones, im in scandalnavia = no u.s. car parts stores..

Need to get new bolts from a hardware store asap and i can't get to the Jeep or the hardware store, stuck at work..

Anyone?

5/16th usually.

The bolts at the pinion strap are 1/4 x 28 (fine) pitch x 5/8 long, with a 5/16 head. The bolts at the transfer case are 5/16 thread with a 5/16 head

Thanks guys
