1971 Demon Radio Brace Question.....
Just going off of what I've seen, but the braces are different from '71-73. The '71 bracket mounts to the back of the radio. I'm in the same boat, '71 Scamp using a '74 radio. On the later year radios, the short end of the bracket goes against the radio and the long end gets screwed to the front edge of the dash frame. You'll have to drill a hole in the dash frame if you want to attach the bracket. For now, I'm just resting the bracket on the inside of the dash. If you want, I'll try to get a picture of mine.
