I yesterday I took the ol girl into the bush. Got a ways in and figured I beat lock in the hubs and about two minutes later I hear a snap, kachunk kachunk kachunk. Looked underneath and the shaft is laying in the tranny cradle. I haven't taken a close look yet but it seems the flange is in good shape still. I'm assuming the bolts are still in it which is fixing to be a real blast. My question is what size and grade are the bolts?

 

If your truck is the same as mine, the bolts holding the front driveshaft to the transfer case yoke are 5/16-24x1.2" with a 12pt head.

 

Being on the 600$ special . Is that 1.2" long or 1/2" long. Seems 1/2" would be to short

 

That is 1.2"; Ford specs the length of them in decimals, most likely just to be confusing.
