I have a 1973 GMC 25 Hundred Super Custom. I know it says 3/4 ton truck but here's the problem the Rear Axle supports a 5th wheel hitch in the back of the bed. I will post pictures, I have the rear axle manufacture numbers but that's it. It has an 11.24 Drum, And napa still can't figure out what it is. Can I get some help guys? Its a 14 bolt. I though it looked like a 1 ton Single rear end. But I could be wrong.
