Russel Machine Shop in Hampton, GA is a good one. Lot of experience with Fords and a lot of ASE certified techs. Highway 19/41 South to Atlanta Motor Speedway. Turn left at the light on Woolsey. At the intersection, Wendy's will be on the left and Richard Petty Blvd will be on the right. Anyway, turn left. Russels will be on the left a couple hundred yards up the road, right past the shopping center on the left.
