Took bellcranks, bushings and bolts to DFE Precision Machining in Clarkston for evaluation. Inside of bellcrank tubes were rough; bushings weren't straight. Larry cleaned up the bellcranks and straightened, reamed and polished the bushings. He also recommended Kluber Isoflex Topas NB 52 as being the best lubricant for the bushing application. Ordered a small tube online.
