Thanks, I got that broken windshield out and found out the P/O stored the truck outside as a result the critters had built nests inside the double walls of the upper cab. Acorns and nesting material resulted in lots of rust, nearly all the Z channel was gone, no choice but to start cutting and welding. Question to someone with more skill then I, are a few pin holes acceptable?
