I found on here that Brown Dog Offroad makes a pretty nice mount for my yj. A couple of questions that have probably already been answered, but could not really find the answer. On the right side mount it has a 1/2" shim, If i use the Brown Dog Offroad ones, would i still use the 1/2" shim? Also, would you guy's recomend using the Ultra-Flex rubber or the Classic Polyurethane one's? Also, Are the B.D.Offroad ones a direct bolt on or does there need to be modifications to fit correctly? Thanks Guy's, James...
