There is another alternative for radios: RetroSound makes a line of modular radios designed to go in old cars. They do this by providing a radio body (which they call a motor), a set of bezels that contain the display and UI, knobs, and a large collection of faceplates to fit a wide range of cars. The radio itself is quite small and uses a very flexible mounting system allowing it to be installed in as many places as possible.
All you need to do is find your vehicle listed and order the proper motor, bezel, faceplate, and knobs. Easy!
Of course they do not have a listing for a 1963 Imperial.
What they do have is detailed dimensions for all of their products. Almost like they understand their target market! After extensive study I found a bezel that looked like it would fit: it was exactly the height of the Imperial cutout and narrower. There was also a faceplate that made the bezel wider but no higher.
OK, this looks like it would fit into the cutout – but how to fill out the hole and make it look decent?
Just a minute – what about 3D printing??? I think my CAD skills have improved to the point where I can do this. Well, one way to find out! Let’s get an order placed.
RetroSound has a choice of three “motors” that are all the same size and come with differing power output and feature sets. I decided that the lowest level Motor 1B would meet my needs. In addition to AM and FM it supports Bluetooth for hands free calling and music streaming. It is the cheapest option, has everything I really need, and is a massive upgrade over what I have now.
Add in the bezel and faceplate that look like they should fit as well as a set of period correct knobs. At this point the cost is around $250. If I can make it work it will be well worth it!
