Its my 2nd go, and its made to fit a GME tx3200. Its a PITA to install, but maybe that'l stop opportunists from ripping it off too
Don't ask how much time this has taken ,the first shape didn't work out, the cb fitted too tight and the antennae cable didn't fit. Now the the antennae cable has a bit of a bend still, but fits heaps better.
This one I took out again and rebended the edge shorter. 1.5mm galvanised plate is pita to flaten and rebend tho. So use this info if you want to repeat this.
Its painted with that hammerd black paint stuff, which I've also had to redo - do use a primer, otherwise it don't stick to galv plate steel.

my revised dimensions


The sheet to which the CB is scewed upon is welded

notice the shape at the rear, it bolts thru to the dash bolts that are in that location, you'll need longer bolts tho, 10mm bolt, 30-40mm long
