identifying a 68 l78 camaro?

[Kurt S]

On the RPO list, I think P28 requiring Z28 was a guess due to lack of knowledge of the option and the fact that Z's were the only cars to get 15" wheels. I removed it from my version - need to generate a new PDF for the site version.

I'd be talking with the original owner - original pics would be go a long way. Any other documentation with the car - like a warranty booklet?

I'd guess Norwood would use DF rallys - the only 15" wheel in the plant. What's the date on the DF?

I noticed the option the other day and wondered why they generated it and why no production totals. Shazam, it appears a week later!
Wonder how the dealer found the RPO - maybe a zone letter? Any one have 68 RPO literature (sales albums, etc) where it could appear? The 4/22/68 price schedule doesn't list it.
