Ferndale 53 I know how much the truck cab means to you being it was your Grandfathers truck but that would be a tremendous undertaking for you if you do not have any experiance in doing body repair of that magnatuide. If the rest of the truck is in good shape I would find another cab to replace it and when it is all done dedicate the truck to him after it is all finished. I am sure he would appreciate your intentions but would realize the effort would not be worth it. But like someone said anything can be rebuilt with dedication and time.
