Hi im doing some rust repair on 1973 cutlass and im in need of a car that i can cut some patch panels out off in central Iowa i can fab them but it be better to have factory if possible. I really need the front upper winsheild channel with inner structure cut about 6 inches back and 6 inchs down on each A piller. There is also an area of the rear package tray that i need on passenger side. Any help would be great!
