I know for a fact that the 1500s and 2500s use the same liners. Pulled the ones I had installed in my '03 1500 before selling it. Installed 'em in my '04 2500 CTD. So, I assssuuuummmmeee that SRW 3500s would also use 'em. BTW, I was a poster on trying to put 'em in the wrong side. Thought for a while that there was a difference in the 1500 & 2500s. Then realized that "R" wasn't the driver's side, LOL!
