well jeff i can't say for sure on your model but i have a 39 with a 53 bed on it other than the bed over lapping the lower sheet metal by a couple of inches on each side "which looks just fine on mine" the fenders line up with the running boards perfectly "and yes i know i will get boo's and hisses from the purist but on my budget i can't afford an original 39 bed" and the stubbyer fenders to me look better.
