Hi. I recently purchased an 88 F150 swb fleetside. The cab and front fenders have some minor problems but the bed is pretty bad. I found an 81 stepside bed and was wondering if there was a difference in styles from those years and if not, would it bolt up with no major mods. I'd appreciate any input. Thanks.

 

Should bolt up just need to swap fenders.I put a 86 bed on 79 with no problems .
