gaylord producing new 72-79 ranchero lids

It is atacted to the front of the bed with 2 hinges with a seal all around. The front is the only area where the water might get in because the window is lower than the bed sides, that is what the gutter inside is for.If I can bet pics I will post them.

 

Thanks for the effort, just spent alot money last year cutting out and fabing/replacing the rusted out back window glass channel. I don't want to create any more problems in that area. But I would like to see pics of what that looks like when installed. are there any factory instructions/drawing for this product?
