I need to replace the 2 bushings in the shock ling on my 86 ATC 250R. According to Bikebandit, they are discontinued. Thes are the ones that go into piece 4 on the Bike bandit blowup under cushion arm, and are piece 5. They go in the arm that the shock hooks up to, not the dogbone part. I noticed that they have them for 87 TRX 250R. Would they be the same, or work? Mine turned up lost, and they are all I need for the rear.
