1966 GT350 Spare Tire Rim Identification

[Craner]

Looking for advice on how to identify a correct spare tire steel rim for a later production car with 14 inch rims

Correct for what Ford installed at the SanJose Plant. 

Identification marks, offset, welded, riveted...
Any information is appreciated.
Thank you

As a spare the typical 66 GT350 used ether a gray painted Hertz style rim wheel ,a chrome Hertz rim wheel or a tenspoke wheel from the factory. The spare was supposed to matched the 4 on the ground. The 66 carryovers wheels were the same as the 65.
