Iirc my 89 EB seats had a nylon spacer (about as thick as a garden hose gasket) between the armrest and seat. So seat, nylon washer, armrest, clip washer, bolt. The center of the nylon washer was wide enough for the shoulder of the armrest bolt to pass through. Itís purpose seems to be to provide dry lubrication at the hinge. I made one from a nylon washer kit from the zone. Had to bore the center out a little with a step bit and clean up with razor blade.
Just my luck, turned the truck inside out and canít find the nylon washer.... guess Iíll hit up the parts store.
