Question RE: core supprt mount bolts - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Howdy everybody,

Need a vendor who can do better than Brother's for a set of mounting bolts and associated hardware for the core support mounts on a 1971 C10 2WD.

I don't need the bushings (I've got nice new Polyurethane ones) but the old bolts were rusted to all hell. Brothers wants $10 for the bolts and hardware, but as in another thread this evening they want roughly $50 for shipping and handling. Which is robbery, IMHO.

We won't even discuss the robbery that is LMC, Golden State, or (ohmyGOD) The Paddock.

The real trick is that I'd like to have them before next weekend (12 - 13 JAN) as I'd like to be able to remount the core support and radiator to see how I will have to run my upper and lower radiator hoses with the Serpentine system I have.

The original bolts are 7/16-14 x 3 carriage head bolts that fit into 1/8" plates which were 1 1/4" square approximately to hold them in place.

On the trucks that we have restored, we reuse the plates and get the carriage head bolts from the local Tractor Supply store. Most hardware stores will have the carriage head bolts.

Since you have the bushings, I would suggest measuring the stackup and getting the right length bolts locally.

If you don't have the plates, they can easily be made by filing the square hole after first drilling a round hole 3/8" in diameter.

Stop by Lowes, they have an awesome selection of grade 8 bolts.
