Replacement bolts for truck bed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

72 Cheyenne402 · 01-05-2006, 03:34 PM

I am going to remove my bed and need to know which bolts I to buy as replacements. I'm sure I'll have to cut the old ones off and replace them. Any help would be great

Thanks

The bolts that hold the bed to the frame are mostly 3/8 x 16, but I would measure them to make sure. The sides and front of the bed are held on with 5/16 x 18. All of them are carriage bolts. Most any hardware store carries them, or you could get a complete set from one of the board vendors. Good luck, Jeff.

The bed to frame bolts are 3/8 by 4 inch. However the front 2 bolts on my 70 were larger, 7/16 by 4, for some reason. Hardware store and some vendors just sell a regular grade 2 bolt, the factory used grade 5 bolts, I would get the stronger grade 5 myself.

I've found that if you make a small spot weld on the head of the bolt to the bed and soak the threads with BP blaster. you can save them. I do know that LMC carries a complete kit for $15.95

I was going to stop by the hardware store on my way home from work and pick them up. so this is what I need 6, 3/8 by 4 inch & 2, 7/16 by 4 grade 5's is this right?

I don't now why Green Machine's had the 7/16 bolts

Mine had 8 3/8" bolts, I just replaced mine a couple of weeks ago.

What do you do for bolts with a wood floor? I know the strips I have are stainless polished. I was going to get stainless bolts and polish them, but you can't get grade 5 in stainless, can you.

Richard, if you can't get the bolts in grade 5 from a board vendor then

It seems that LWB beds have the two 7/16 bolts up front and SWB have 3/8 bolts in all holes.
