Sorry about the thread-jacking, I got carried away.
Good news, went to the yard this morning and found what I needed. A straight and relatively solid windshield frame.
(Will return Monday with a portable sawzaw). Started unbolting the roof, and I was able to bend the whole truck in half!
The bedsides were so rusted that the roof was the only thing holding them to the truck! Well this is gonna start to get interesting. I think it's time for me to start my own thread.....
