exactly, make sure to take the box off and take a good look first to see just whats left, then media blast and use acid etch primer/sealer to protect it from then on, unless yer better off replacing it,
you may find doorskins, cab corners are common , but not on mazdas, get a shaping hammer and build yer own parts for that.
Take a good look at the frame, with that kind of rot I would be cautious.
A little wire feed Mig should'nt cost too much I spent 400.00CDN on a lincoln flux core, good for sheet. I need a bigger welder for suspension fabrication now though. Buy a big welder 240v Gas assist if ya can. Check the classifieds.
