4 Runner Suspension Retrofit (looking for bushing)

I installed the front Billie TRD Pro Shocks and the rears need to be rebushed. Does anyone have the part number for the appropriate bushing. I know this has been done on the forums before, but I have found no information about this illusive bushing folks are using to allow this swap. The fronts are a HUGE upgrade compared to the OEM SR5 suspension. Night and day difference in ride quality, cornering, bumps, everything. I'm stoked. I do not believe I've lost any lift as the shock was over an 1' longer than my OEM. Photo for reference.

 

I also have a set of fronts from 4runner for my tacoma - The lower bushing is too wided - how did you get yours to fit?

I was assuming I could get a tacoma spectific bushing - but does not seem to be available as a seperate part from either FOX or Toyota.
