On the wheel back-sides: 11" would have 10214047/AFS/JPN, 9 1/2" would have 10214046/AFR/JPN

I will check today and Thank You

Ami......yes.....me too........I have A-Molds on everything that has front brakes converted to C5-Z06 Front Calipers with Wilwood Rotors as that is required because Saw Blades will touch the C5-Z06 Calipers (about 1/4 inch interference).
After Market Chrome A-Molds on a 91' and Painted Stock A-Molds on a 95' both work with C5-Z06 with Wilwood Rotors Conversions.
See Item #13 ZR-1 (90' and 91') Wilwood Rotors and C4 to C5-Z06 Conversion
13. Wheel Dimensions that will fit on this brake Set-Up.
This would be the limit of a wheel inner dimensions which would fit/clear the C5-Z06 Brake Caliper Set-UP.
Rather than try to measure the offset and the maximum radius of the Caliper it was easier just to measure the
A-Mold wheel which just clears the spokes as well as the C5-Z06 Caliper outer radius as shown below.
I would say this is Minimum Clearance. The clearances of this Set-Up is on the order of 1/4 inch on spoke and 1/8 inch on wheel inner radius so very close. There is slop in the Caliper pins riding in the bracket so this clearance is definitely required.
14. Will this brake Set-Up work with Stock Sawblades.
I measured a
stock Sawblade wheel and found
the inside diameter of Saw Blade Rims is about identical to A-Mold Rims at the two critical locations of the Calipers. I also measured the spoke Offset from the Hub and found it to be .75 inch as compared to 1 inch for A-Molds. When installing the Sawbade wheel
the spoke of the Sawblade JUST came into contact with the C5 Z06 Caliper as shown. In other words I would say
the offset of the stock Sawblade wheel is 1/4 inch short of what would be required (3/4 inch vrs 1 inch).
It would be easy to place a 1/4 inch spacer on the Hat of the Wilwood Rotor but you would then be 1/4 inch shorter on the stud length for the wheel nuts which you end up with 1/4 inch less than the bit over 1/2 inch threaded contact now (as I view my Hubs with the Wilwood Rotors installed with Hats).
