1964 1/2 K-code 15 inch steel wheels

here is link to a motortrend story about a test done in 64. This car had 15” wheels but I’ve seen references to the wheels were to be offered, but never made the final cut.
Would they have been what Shelby used in 65?

Correct steel wheels for 65-66 GT350's ???

Hey Folks,

I have a deeper than my knowledge GT350 question for the 65-66 GT350 experts out there. I need to know what are the correct steel wheels that came on the 65-66 GT350's if they didn't have the Cragars, Torque Thrusts, or Magnums. I'm assembling the final parts I need for my next project, a '65 Carry-over car, and I plan to use the plain steel wheels as shown on the car in this link:

I've located a set of Kelsey-Hayes 15x5-1/2 steel wheels…

The 64½ Mustang in the Motor Trend article was a pre-production to show car magazine editors what was coming. Differences from production include C3OF-AJ carburetor with appropriate exhaust manifold with heat chamber (automatic choke), Fairlane 289 High Performance fender emblems, painted valve covers, small generator pulley. In short, it is a mixed bag. Has the California closed ventilation system. By June, when the production K-code Mustang came out, carburetors were C4OF manual chokes, deifferent fender emblem backing plates, and chrome valve covers.
