i also bought rear fenders room r+r. my truck is a 46. i recieved the fenders and they had pitting and cracking in the jelcoat and no lip in the wheel opening. icalled r+r they said they didnt know what to tell me, the mold were made off of original fenders they said i could return, but iwould have to pay return shipping plus 30% restocking charge. not made of money i could not afford to return. my body man went to work on the fenders and templated the wheel openings and found the openings egg shaped and compeletly different side to side also. be very careful !!! never again for me
