Stopped for thought, then grabbed a soldering iron, warmed them up & yanked them out. Cool trick, the molten plastic collapses on itself meaning the hole will still be small enough to hold the new screws. I say "Yank" them out, don't try to unscrew them as you'll either make the hole bigger/misshapen or the molten plastic will bind to the screw (Cos you're taking too long) & you'll end up breaking it off flush with the chassis & never get the rest out.
There was also an issue with the motor plate tappings being stripped by a previous ape, so another trick was called for here (Contemplated just remaking it, then decided I'd rather keep the original) - Using a tubular punch, just slightly bigger than the tapping, put the plate on a hard metal surface & centre the punch around the tapping & give it a thump with a small hammer - this shrinks the hole allowing it to be used again (Same method they use for assembling cheap rose joints).
