1970 Duster project in Sweden
Txstang84,
Yikes $586 a side online. If you use a good epoxy etch primer, and weld thru primer in the spotweld areas that would work as well as galvanized steel. If you plan on living in abilene/potosi area it wont rust out here. I know i can get you half quarters like my goodmark cuda ones pretty inexpensively, about half the cost of full quarters if your interested.
I plan on using that spray sound deadener on the insides of the quarters too. I can hide the nonstock seams that way.
