69 Firebird Quarter Panels

[simbad's68]

I'm in need of quarter panel and door skins on my 69 Firebird. AMD produces the door skin, but do not produce the quarters for the Firebirds. I have located a passenger NOS quarter for $1000, but I would still need to purchase the driver side in an after market quarter. All the research I come across references the Camaro. There seem to be limited information on the fitment of the after market panel for the Firebird. I'm hoping I can get some feed back from individuals that have came across fitment issues, and the quality of panels. Any help would be greatly appreciated.
