I have found Briley's Tire the best place in town. I take our stuff there when I don't want to do it or can't. It is on Trade Street off Memorial, but, if you come from town on Greenville Blvd. you turn right at Golden Corral. I your son doesn't know where that is tell him it is just down from Hooters!
If it were me, I'd have them do a compression check as well as get it up on a lift to check out the suspension, brakes along with hoses, belts, transmission etc. I don't know what they charge, but will call and let you know. PM me with his cell number and I'll help him. If he just wants someone to drive the truck and give an opinion, I'll stoop and drive a Ford.
Do any of you other NASCAR Rednecks love the way Harvick passed Johnson? It reminds me of how the 3 car would have done it. Push the guy down the straight to "rattle his cage" and get him loose. Then, pass him on the last turn.
