Has anyone ever replaced the threaded pin/metal bushing setup with a rubber or polyurathane bushing? I'm thinking of going this route on my 52 3100 1/2 ton but haven't been able to find a manufacturer online that lists the ID and OD of their bushings - they all seem to do it by vehicle type/year only. If I could find a bushing with a 7/8" OD and a bolt hole in the middle I'm pretty sure I could get it to work.

It seems like a modern bushing setup would give a slightly softer ride, less maintenance, and allow the shackle to be attached at both ends instead of only by the bolt in the middle. Thoughts?

Thanks,
