They look like 15" rims. Were the 15" Rallies that were standard on Z28s an option for any other model also?
SS were F70-14.
Nope. Only Z/28's got 15" wheels, except for COPO 9737 Sports Car Conversion, which was available only with COPO 9560 or 9561.
Quoted from Bill Glowacki's COPO report...
"Yenko Camaros also featured another COPO, the 9737 "SPORTS CAR CONVERSION" which included a 13/16" front stabilizer bar,
15x7 rally wheels with E70x15 tires, and a 140 mph speedometer. COPO 9737JD had an initial list price of $126.40, later raised to $160.10, then $184.35 when a factory tachometer was included. At least 2 ZL-1s were built with COPO 9737, as were some of the L72 COPO's ordered by other dealers."
