Time to Buy Tires for the Duster......help please.

I don't know if I can find anybody to try tires. Maybe I could ask around as I get closer to dropping the body over the engine, K member and front suspension. That's the time that will definitely need to have 4 tires. Back in the day (1980) the car rode on 14 x 8 Cragars with McCreary J60-14's with a drum spacer. It was a tight fit but it worked.
