Yes, and my SS did come with 14" Rally wheels. Chassis Broadcast Copy documents it.
I wonder if it is a LOS GMAD vs Chevrolet NOR thing. The part number you have according to the AIM is fro all other wheels besides PW7 & PW8 F70-14 tire options. Which option code does your broadcast sheet reference for the wheels?

I looked at the AIM pages and found something. It must be a coupe or convertable thing. My car is a coupe, yours a convertable. Also the AIM page PW7 A1 is showing a convertable, not a coupe. The standard SS wheel was a 14 x 7 painted steel wheel and cover and F70-14 tires. 14" x 7" Rally wheels were option ZJ7 and stamped YJ. My broadcast copy has "YJ" in box #287 wheel size, my wheels are stamped YJ.
Page PW7 A1, must be for all convertables and SS convertables with larger F70-14 tires. Notice the jack base is right side up on your sticker 3949515 and page PW7. Standard tire convertables have the jack base upside down into the wheel and sticker 3949513. The coupes can fit the larger tires with no change, so only one sticker 3949506. Thats why you need the spacer, because the jack base is right side up and the wing nut needs a bigger contact point.
