bkhpah,
You may be 100% correct. I think that there may be more to it ,however.

It just wouldn't follow that a dealer would create additional work for himself when it wouldn't be required.

I have asked Jack Douglass this same question, as all his Direct COPO orders were X-11 coded.

He remembers that his COPOs arrived without the X-11 pin stripes, but recalls somehow designating them to be pinstripe delete(per Don Yenko's order format).

I would not agree that the pinstripes would be 'easily' removed by buffing them off.

While an accomplished professional could wet sand them flat and finish them off with a buffer,your standard dealer 'prep' or 'get ready' personel, as they were commonly called would not be allowed near a new car with a buffer.

Since these were all batched special orders (not built one at a time)it would make sense to me to have a pin stripe delete for Yenko Camaros.

Is your original paint Yenko X-11 coded?
