Sizes of Thumb Wheel Radios

The pushbuttons can be swapped for chrome if you want. You can find good used ones, and I believe they are or have been repopped.

The big chrome mounting bezel can be removed. There are two big, beveled bolts which appear to be missing on your radio. Also, there a few small bolts, which are there. If you like, I can send you my spare mounting bezel so you can see if it will swap with yours and fit your dash. It's the one in the fourth picture in post five. I think it will be what you need to mount the front of your radio. If you like it, and want to keep it, send me a few bucks. It is pretty badly pitted, so if you don't want to use it for other than test fitting, you can send it back and look for a nicer one. At least you'll know what you need.

If you'd like to try my spare mounting bezel/bracket, send me a PM with your address.
