I got a flowmaster exhaust kit and am happy with the fit. I just can't figure out the rear hangers that are on the axle crossmember. Before i just drill some new holes i was hoping i could get a confirmation i'm not backwards? They seem to be for a not off set muffler but this system only works with offsets. If i do have to drill is there a better hanger? This set does have push on washer things to lock it but seems like it will be problematic in the future. Yes i do have clamps on the part that these should go so i could assemble it all.
