Any long-term mechanics out there who can address the belted vs. radial replacement tire issues on these birds? Any alignment changes necessary to AMA spec when switching to radial, or back?

I don't need radial tires for high speed or high performance on this car and am considering restoring the factory look of belted tires. If I can remember correctly, the tubeless belted tires were more prone to puncture but easier to repair, and had stiffer sidewalls when properly inflated.

Will gas charged shocks affect my decision? They weren't available when the car was new, but add immeasurably to its ride comfort.
