Buddy,

My 01B has YH's. As far as dates go, they are all Dec 17.

Hope that helps.

12-17 and 12-18 are both good dates. not sure exactly when the change over from AD to YH was.seems that 12-18 would be in the third week.

Are Dec. 17 1968 "YH" wheels to late for a 12C 69 Z28 ?

My 12C California car came to me in 75 with a 12/18/68 YH wheel and original tire in the trunk. The other wheels had been changed.

 The last AD wheels were dated 10-24 (68). And as mentioned the YH wheels started 12-17 (68).

Mine is a 12D Norwood build and has original YH's on it.  I discussed this with either William or Kurt a while back on here and was determined to be a good date and it helped them determine the change over to YH at least was occurring 4th week of December.  I don't remember the dates on the wheels now and they have been removed and packed away, but that thread is on here somewhere.

How would the plant have handled this change? I'm thinking the broadcast copy would have "YH" on it where previously it would have had "AD". So the assembly line would change to the new correct wheels.Would there be some kind of internal plant change notice? What would have been done with any remaining unused "AD" wheels? Service parts or ?

Are they really American Racing wheels or do they just look like ARE's ?
Don Yenko had his own wheels cast at the ATLAS Aluminum foundry, the patterns were taken DIRECTLY from an ARE Torque Thrust. If they look like ARE's but have no manufacturer name cast into them they could be ATLAS wheels. I believe JOE on the Yenko site or Brian Henderson at SCW in Latrobe would be the best people to ask.

I would BET that the change notice would have said something like 'Exhaust supply of 'AD' wheels and then change to 'YH' wheels...  I've never heard of an AD wheel being purchased OTC...  Has anyone else?  I'm not recalling the specifics but they made the change in the wheel to accommodate a change on another part.. was it caliper interference? or ??
