    I know this maybe a waste of someone's time, but I was wondering what size bolt is used to attach the front driveshaft (for an 84 Blazer) to the transfer case (NP208). Any help is appriciated.

    The bolts that hold the shaft on on my '83 K20 with a 208 take a 5/8" wrench. I think the bolt size is 7/16". I know they aren't metric because I just built a new front shaft for my truck and tried to use a set of new 12pt, 12mm bolts. They wouldn't screw into the flange.

    The M12 bolts are the ones used on the flanges like HAD sells. 12 point, 12mm metric wrench to remove them.
