RetroSound Redondo RS Radio in 1967 Barracuda

Oh, cool. I'll check it out. My son is in the middle of assembling it.

UPDATE: I checked out the video, but that was one the thumb rollers. I have the shafts. I did see how they mounted the strap though. That was good to know.
I just picked one of these up as well. Did he have to trim the bracket were the push buttons would attach? The bracket has two rows on part of it and only one another it seems like it would have to be trimmed for the buttons to line up for installation as far as depth? Just thought I would ask before making a cut..
