I bought mine from these guys Carjunky.com carjunky - Auto Parts and Accessories Catalog - Door Hinge - Suzuki Sidekick Door Hinge
I ordered a set for the drivers door and they were around $25 delivered to Nova Scotia Canada. Took about a week to arrive, I bought the cheap ones that were 5 or 6 bucks each. You can buy hinge pin replacement kits with new bushings and pins at most auto parts stores. Some people use old valve out of engines to replace the pins. good luck
