Iron Resurrection - Season 4

The Martins face the physics conundrum of trying to fit a 6'5" former football player into the cab of a 1967 Chevy C10. This tall order requires customization of the firewall, motor, frame and interior, plus a custom paint job.

With a deadline quickly approaching, the shop struggles to fit a gigantic ex-NFL player into a tiny 1967 Chevy C10. This oversized job includes a customized leather interior, automated bed cover and a transformative paint job.

Joe is world renowned for building badass motorcycles, but on this build, he's pushing his engineering chops to the limit by building a monster trike that would look right at home on the set of a Mad Max movie.

Shag and Amanda get a '65 Chevy II Nova for a steal, but as the team digs in, rat nests and rust are the least of their worries. The build requires a complete overhaul and has them thinking they bit off more than they can chew.

Fitment issues in the engine bay leave the entire shop scratching their heads. Joe has big plans for the '65 Nova, but a small space to work with. It will take a lot of ingenuity, and a little cussing, to tame this nasty Nova.

A customer wants to surprise his wife with major upgrades to her '68 Corvette convertible. But working with the fiberglass body soon brings on headaches that threaten both the car and the shop to crack under the pressure.

The clock is ticking to complete a 1968 Corvette convertible, but messy fiberglass repairs uncover major collision damage. And if that wasn't enough, the customer wants an all-white interior -- not a good fit for such a dirty job.

A time capsule rolls into the shop in the form of a 1983 Silverado with exactly 69.2 miles on it. The owner passed away last year, but now his daughter wants to finish turning his truck into a modern muscle car under the hood.

Amanda and Shag restore a '73 Vega to its former glory. They add a huge engine to turn it into the perfect street racer, but first they tackle the rust and grime.

Joe and the team race to complete the 1973 Vega transformation in time. This is the biggest and most dramatic project they have ever taken on.
