RetroSound Redondo RS Radio in 1967 Barracuda

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..

The L shaped brackets where the shafts attach? Yeah, they needed to be trimmed. I have a thread some where here with tons of pictures.
