Why check your vintage U bolts
I purchased my 58 Overlander from very close to my house so I didn't think there was a problem with towing it the five blocks. Well luckily it held together. I replaced the brakes, shocks, wheels, tires, and recut the drums.
After doing all this I noticed that the passenger spring didn't look right where the bolts went through. I took off one of the shackles and found that the rubber bushing inside was shot. No problem, I order new nylon ones. Well when I went to remove the u bolts from the spring I couldn't tell what they used to bolt them on with. They looked like they had used some sort of press on clip. It was very thin and pefectly round. Below is what I removed these are whats left of the factory nuts. The drivers side u bolts and nuts didn't look that bad but why only replace one side. When I went to remove those they both snapped in half with very little effort. I hate to think of what this would have done to the undercarriage.
I hope this will help someone else and keep them from having a major problem when it's such a minor fix.
