EXH. FLANGE BOLTS

1971 GMC Truck • V8 2WD Automatic • 180,000 miles

Been having trouble finding what size deep well socket to use on exh. Flange bolts on '71 GMC pu w/ 350 auto/ in between normal sizes-even tried metrics, all either too big or small// Not 1/2 " 9/16" 5/8" Or 13, 14, 15 mm's either- tho I know they have to be SAE// Special socket.

It it a through bolt, head of the bolt on one side, nut on the other? If so, cut it off, oxy-acetylene, or use hammer and chisel. You can always get another nut and bolt.

If the bolt goes into a blind hole, you can't cut it.
