I am wondering if any of you have the Custom Autosound stereos in your Cougars. I have the padded cosole and stereo surround in my '68 and want to make sure I make the right choice. I have been shopping on WCCC (what would we do without Don, Linn, and the boys?) and have narrowed down to either the USA-1, USA-230, or KHE-300. Do any of you have an opinion or advice?
