There should be plenty of 73s around. I suggest you take your time and get a good one that is free of any serious rust. Spending a grand or two more will be a GOOD investment compared to what you'd put into rust repair.
Just wait, you'll find your girl local. Unless that's your end goal, rust repair/fabrication ain't hard, nor is it expensive if you have the place to do it.
Also check inside the 'A' pillars if you can. Mine was loaded with rust. Especially if it was vinyl top.
