As MN Ben said topline in Paramount, Ca. I replaced mine and they were a big help. Now I was able to drive there to pick up so you would have shipping to deal with. I have a 95 and wanted a excat match due to mounting points and they had it. They told me where to find a tag with a number and they have a large data base to match your ladder. Where mine mounted to the camper at the bottom there was a tag and number, it was inside the plate so when I removed it there it was. Fit perfect right where the original one mounted, not cheap but excat match. Good luck
