I'm the third owner of a 1967 Mustang Fastback survivor car. In a container of parts that came with this car was a BF Goodrich collapsible space saver tire. In my research, I found it to be for a 1970 AMC AMX but before I replace it I wanted to be sure. FOMOCO is nowhere to be found on the rim, but stamped in the metal is a K2 over a 2 and a 2 on the left side of the valve stem. On the right side of the stem is a 20 and a 50. Then there is a K2 over a 1, LS, N, and a 12 stamped into the metal. The tread has no wear. Any info would be appreciated.
