[FC] Rampside Ashtray Mount Butchery HELP!!

[D]

Some previous mechanical/sound system engineer decided to install a large
magnet speaker in my '62 Ramp. To get it into the dashboard he/she removed the
Ashtray mounting brackets. There are also 2 holes in the dash, on each side of
the ashtray opening. They were covered with a metal plug. I have no idea what
the brackets look like. I'd imagine, that the bracket was probably welded to
the dash. Can someone send me a photo or a sketch of what I'm trying to
replace ?

THANKS !!
