Does anyone know of what spring u-bolt that can be used for the USMC welded shackles on the front bumpers of the M37?

I was hoping I could cut the threaded area of a leaf spring u-bolt off and use that as the weld on USMC lifting shackles.

I don't think it was anything special. Just a bent piece of steel dowl. Maybe 3/8th or 1/2 inch thick? Not sure if they came from the factory that way for the Marines or if they added them at the local level.

That's what I was thinking but am not 100% sure on that.

Here's another link for you. This one may be of some (more) help to you as it is picture heavy.

I was told by an X-Marine that they were made from a leaf spring shackle bolt from a early type military vehicle. The cold role dowel, if I can find out the diameter, id probably the easiest way to go. Getting a perfect u-bolt bend is the hard part.

I'm just spit ball'n here but if they used old spring "U" bolts then they were probably out of old 2.5 ton trucks such as the International harvesters or even CCKWs that they received post war from the Army.

For making the nice round bend on your "paper clip" lifting shackle, try bending the rod over an appropriate sized peice of pipe.
