RetroSound Redondo RS Radio in 1967 Barracuda

Hey @dboldt I had a question for you regarding installation. I hope you're still around, since this thread is a bit old.

Anyway...

Once you had everything (buttons, display, shafts) mounted onto the body of the radio and you put it up into your dash, did you use any nuts on the shafts to tighten it to the dash? I hope that made sense.

Or... is the only thing holding the radio in place the strap that attaches to the back?

Thanks!
