Anyone know a good souce for these. Mancini has the bushings but is out of stock on their in-house bolts. Any others I should check with?

U bolts should be pretty easy to find at any shop that does springs, rear-end work. After market truck shops that do lift kits, etc have a good selection. I found what I needed at Autozone.
The shackle bushings can be ordered from Firm Feel, Just Suspensions, PST, etc. Even local parts stores might have rubber bushings. You will need to measure the eyelet diameter. I believe the bushing sizes for the front eyelet came in either 1 1/2 or 2 inch and the rear eyelet came in 7/8 or 1 inch. If you're doing bushings, going with polyurethane would be a good upgrade. I had put in polyurethane bushings in back in 1991 and when I changed leaf springs last month I was able to pop the urethane bushings out and put them in the new leaf springs! Try that with 12 year old rubber bushings!

Autozone? No kidding....I looked on Partsamerica.com (Kragen) and they didn't even list the category, so I assumed I would have to go to a dedicated source. Well, looks like I need to do a bit of local shopping this weekend to see if I can scare some up!

Well I am up in Michigan and and there is a shop up here called John R Spring and Tire center in Troy Michigan. I was just in there today and they will make any U-Bolt set and stock all types of shackle bushings.

If you want to give them a call here is there info...
the charged me $5.50 each for the U Bolts.
