I am working on my 1957 Jeep FC 150 and found a loose bolt that holds the pickup box down. It is frozen and rattles. I can't seem to break it loose to tighten it. I have been spraying Kroll oil on it to no success. Is there anyone that sells these bolts. This appears to be a carriage bolt with a large head. The jeep parts book says "GM-109024" 3/8-16 X 1". I really want to replace it unless old trucks are suppose to rattle?

Thanks for any help

Gordon,
If the end of the bolt with the nut on it is relatively accessible, you might be able to drill a few small holes in the web of the nut, and then split the nut off the bolt with a coal chisel.

That way you can save the bolt.

Start out with a small diameter bit: 1/8” or so.

Try to keep the holes back a little further from the bolt shank than you think you need to to avoid damaging the threads you are trying to save.

Nut splitters are available, but I’ve always had very good luck with this “drill and split” method.

On my '170, I used regular bolts--don't remember the size--with washers and a self locking nut. The bed to frame bolts on my truck were rattling because the 'rubber' bushings between the bed and frame were missing. The bushings look somewhat like rubber doughnuts. Walcks had replacements on my doorstep in just a few days.

Removing the bolts on my truck was annoying. There wasn't enough clearance to get any kind of ratcheting tool onto either the nut or bolt head, so it was turn the wrench about 1/8 of turn, flip the wrench, turn about 1/8 turn, flip the wrench for about 2 inches of fine thread bolt.
 
Well last night I finally fixed my loose bolt issue. I took a Dremel tool with a 90 degree attachment with a cutoff wheel and cut off one side of the nut then I was able to take a long screwdriver to break off the remainder. With the bolt loose I was about to run a tap on the bolt. Reassembled with a lock washer and new nut. Finally got it done!
