70 dart 470 ci drag car build.
I got a little more done today, nothing is really done, just chipping away till it's done.
Went at the undercoating with a torch and scraper. FYI that's the slow clean way. Fast dirty way is grinder and braided wire wheel.
After I cleaned and wiped down with lacquer thinner I cut some relief slits on the outer tub in order to push it out towards the quarter panel.
Had a oh **** kick back with the grinder in tight quarters...I always love that, After I finished that I gave the quarter panel a bunch of(strategically placed) cuts to bend in for a lip and surprisingly the metal bent straight.
I will make filler pieces for the inner tub and weld the tub to the quarter panel and leave 1/4 inch lip.
