I have a 1969 Pontiac Firebird and had a hard time finding a radio. Finally got a USA-740 from www.vintagecarradio.com. It came in about week after ordering it and plan on installing it tomorrow. Will let you know how it sounds.
Thanks for sharing Bob, looking forward to hearing back on how it sounds and works. Am also interested in the fit and if you had to cut the bezel at all as all the others in the past that I have seen required a little bit of cutting. Please post some pics also if possible. Thanks
