Are the regulators both door and quarter interchangeable between a 68 Camaro and a 69 Firebird? Both are coupes with standard interior.
Thanks Bill

Basically they are the same, but you have to remember that the 67 has the vent window, making it the only exception.
So 68 & 69 are the same.
The rear windows are the same for all three years.

So the answer to your questions is YES!

Thank You My car is done and and I have a set to sell and did not want to tell someone they fit and was wrong. Thanks again
Bill
