My 92 NSX has worn bushes on the right rear lower control arm. A trip to the local Acura dealer revealed that these bushes are NOT listed as a spare part but they did offer to sell me a new bracket(part number 50220-SL0-000) complete with new bushes for around $1300! Has anybody had this problem? There must be an aftermarket source of rubber bushings out there somewhere. Any suggestions greatly appreciated.
