Need help with rear upper control arm bushing

[MotorcityCobra]

I picked up a 9 inch rear from a cobra that had a thermal event in the engine compartment. It has the brackets similar to the 8.8 inch, but the bushings between the upper control arms and the axle are different. These bushings (I took one of them out) do not have a metal sleeve on the od, and have a slightly smaller od. Overall length is about the same as those used in 8.8's. Would anyone have a clue as to what these may be? I could use the old but prefer to replace. Thanks.

I had to replace the strangely mismanufactured upper control arms on my West Coast and found a large variety and selection on Suicidedoors.com.

Good luck!
