I just found a radio/with speaker under inside of unit that will go into my 53, 3600. This is a old radio and I'm told it works. (?). How was it tested....Would a 12volt test be the way, or 6volt test.(She's compleatly stock, 6 volt sys. and ALL new new wireing, thanks to CD).If it is 12volt, I'm thinking of hidding a small cycle batery under the seat, or glove box, and just mantain it....Any ideas..You guys are all like Dr. House to me,...(we'll talk about my back later) Thanks Four Time...Paul
