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.

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

[iluv69s]

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?

[al8apex]

the extrapolation method is NOT accurate

ask a math whiz why

[1969z280]

Extrapolation will provide a reasonable estimate when no other data is available. Accuracy is relative and better than guessing, suggesting or supposition.
