Hello all. I got several step vans im working on. From 65 to 72 year models. Im trying to track down some orginal floor plate. I. Replased the floor in one with diamond plate but it needed a new floor front to back. The 67 im working on just has one bad spot i want to try to save the floor. The metal is a type of diamond plate but has a square pattern instead of the more modern recognizable diamonds thats out there today. Ive exhausted all my leads. Called every metal supplier on the net i think. Does anyone know where to find it if its even manufactured anymore ?
Thanks in advance
