Just got my 9" back from strange engineering, shortened and new axles. they do beautiful work by the way. what I need now though is, the bottom plates to mount the rear end in the new leaf springs, and Ubolts to fit this rear end.
U bolts can be scored at your local NAPA. CJ's did not carry the diameter that I needed.
If you are also wanting to add a good traction bar, a few include (and have attached) their version of the bottom plate. Caltracs and Slide-a-links come to mind.
If your housing has the necked tubes, the 65-66 U bolts and plates will do. If you have the straight tubes, 67-70. If you have something non-stock, what diameter are the tubes?
