Car Fix - Season 12

Fuller and Bumpus fabricate a desert-style spare tire carrier for the massive MegaRexx MegaRaptor truck; the 46-inch tire weighs a ton, and they show how to design and fabricate using the latest tools and equipment.

A Buick Roadmaster woodie wagon is getting a complete restoration, and the guys will show when a body panel is worth saving and when it needs to be scrapped; they also bring some of the old wood back to life.

Jeremy brings in his mom's 1965 Mustang for a V-8 swap; they'll take out the factory motor and put in a 302, then install a complete front end in it with coil-overs to give it a much smoother ride than the factory suspension.

Fuller and Bumpus bring in a rare '50s mail truck and completely rebuild the front end out of metal; they also take a trip to a nearby car museum to see one of the first all-electric mail trucks ever, which was built in the '70s.

Fuller and Bumpus demonstrate how to take modern design techniques like flush-mounted glass and custom drip rails and convert those elements onto a 1986 Monte Carlo.

Some project cars need every body panel replaced, so Fuller and Bumpus show how to work with new sheet metal panels on a 1963 Impala; they also find a running Road Runner to have some fun with.

The guys bring in a vintage 1979 Jeep that is being sent to auction to give it a finished interior with carpet and panels; Jeremy uses a sewing machine to bind the carpet edges.

Fuller and Bumpus bring in a 1959 Ford Edsel and take out the stock transmission to put in an automatic overdrive and give the classic car extra shifting power.

The guys pull apart a transmission to show the wear items, and install a performance clutch on a modified Chevy.

It's hard to go back in time if your DeLorean isn't running, so Fuller and Bumpus bring in a 1981 DMC-12 and, with the help of some DeLorean experts, get this famous movie car running again.

If you ever wondered how to fit a wide tire under the back of a classic muscle car, today is the day. Bumpus and Fuller build a mini-tub for '67 Dodge Coronet and show you a special tool you can get to find the correct wheel size.

Fuller and Bumpus bring in a very clean S-10 and build a custom roll pan for it. They finish the AC system that Fuller had already started, and then they show you how to lock up the rear end and do smoky burnouts.

The guys take the old steering out of a '66 Volkswagen Type 2 and bolt in a new upgraded rack-and-pinion setup. Then all of the MotorTrend hosts show up to check out 20 years of Bryan Fuller builds at the Forged by Fuller exhibit at the Savoy museum.

Fuller and Bumpus take a '70s Datsun truck and build a new rear frame section to lay frame on the ground; then to finish it off, they cut the roof and make it a convertible.

A six-speed manual, almost 700-hp car can be found from the factory; it's called a Cadillac Blackwing, and Fuller and Bumpus bring one in to build multiple removable racing-style exhausts.

Fuller and Bumpus are accomplished motorcycle builders, so they show off some of their skills on Fuller's newer BMW R 18; they tear the bulk off the new bike and build custom fenders and other accents to give this modern bike a vintage BMW look.
