I have a 55 Chevy with Vintage air and Raingear wipers. I would like to know if anyone has this combo and has a Retrosound radio? Does it fit? I know space behind the dash is very tight. I mounted a stereo under the dash and air vents in a home made console, but I would rather have an in dash radio. I need the floor space for feet. I have added kids since I built the car and now we have 6 people in the car. Thanks.
