Does Anybody Know...

How many 1969 Camaros were built with both RPO codes Z22 and Z27 (RS/SS)?

[Mr70]

According to Chevrolet records,37,773 were built w/Z-22...34,932 were built w/Z-27.
I don't think they kept exact records of how many Camaros got both of those together,other then the 3,675 (Z11) pacecars replicas that did,so if your including them,start from that figure up.

As stated above, there is no way to determine how many combinations of RPO's were built. There are no records of that. Same for number of colors with any RPO (like how many black z28's were built). Massaging the numbers through percentages is not accurate either.

Extrapolation is as close as you're going to get to the number. It's not the actual accounting but it will be a reasonable estimate. Example: if half of a production run (50%) came with a certain option and only (10%) came with another option, it is reasonable to assume only 5% came with both options.

Thank You guys for your help.

This would be statistically incorrect, as the 50% would have been taken from the total production, as would the 10%. Hence, taking the 50% sample and then applying the 10% figure that was initially derived from the population (total production) would give you an F in statistics class.

By the way, I received an F too at some point, but this I know to be true.

The problem with using that method, is that it is easy to option out to &quot;one of none.&quot;

A good example of the problem with extrapolation is my 67 Z.

Assuming only 602 Z's made...and my car had the ultra rare shoulder harness...omly 400 and some made..(I do not recall exactly)....

the problem with extracting the percentages is that apparently most of the cars with the shoulder harnesses were the Z's and 375 hp cars...for good reason !!!

One of none?

Yep, take any highly optioned car, especially one with an uncommon option, like fold down, and an uncommon color, and start multiplying out the percentages. You will end up with one of less than .5, or essentially &quot;one of none&quot;.
