1969 sheet metal- quarters
 

I am just starting my 5th major Camaro rebuild and would appreciate feed back from other members. Up to this point, I have been lucky enough to have all GM metal but I'm jumping into a '69 convertible that is missing a quarter.
I searched on line and see some NOS listed for big $$$ and also see the Good M brand at a much reasonable price. My concern is just how good
to the Good M convertible panels fit or if someone knows where I can find NOS quarters at a reasonable cost?
