Bed mounting holes

So I am getting a cucv frame ready to accept my 75 c30's body and I seem to be missing the second set (starting at the rear of the cab) of bed mounting holes on the frame for the bed. Is this normal?

Re: Bed mounting holes

Just looked at my CUCV. The 2nd set of bolt heads is about (by eyeball) 1.5 feet behind the 1st set. A fair bit wider spacing then the 2 sets at the rear of the bed.

Re: Bed mounting holes

if the box is already on the truck, you prob can't see them as their hidden behind a crossmember. these are usually the big long bolts if you bought a bed bolt kit.

Mine are 2 ft apart in the front where as on my c30 frame they are 11 inches apart.

I'll take a look again. I did get two longer bolts in my body lift kit and it wasnt readily apparent as to where they went.

Re: Bed mounting holes

The 11 inches matches what my 75 C10 has at the front. Don't know if the CUCV beds were different because military, or a 84~86 K30 thing. I had always thought the beds were pretty much interchangeable between like bed style trucks.

Maybe just set the new bed on the frame, stab the 6 bolts that match and mark and drill the two needed holes.

Re: Bed mounting holes

There are 2 different bolt patterns for that 2nd set of bolts.

Yeah I had a friend measure the front set of bolts on his mid 80's square and it matched up with the holes in my frame. Nothing a drill bit cant fix though.
