I finished installing one today in my 53 3100. Retrosound from classic chevy truck parts of america. I orderd the retrosound classic model with stovbolt discount it was 189.00. I opened the box and it was the retrosound zuma model which is more expensive. I don't know why they sent me the better model but i was fine with it. Comes with faceplate and knobs for the A.D. trucks. Looks nice works great. I bought the 2 speaker setup that fits in the orginal location. I put one in my 65 mustang a few yrs ago and was real satisfied with it. You can check them out on the web at retrosoundusa.com. The classic model would be fine and is the cheapest one they have.
