I just saw an AD GMC 700 series truck at the ATHS show.
It had 6 lug hubs I believe, but then it had these cast spoke adaptors on both front and rear that allowed the truck to use open center Dayton type wheels.
I believe the adaptors were made by someone other than GMC, but I forget who.
Any how, I want to know if anyone has, or has seen some that have the small 10 lug pattern like the 1.5 or 2 ton AD trucks do?
