In what is one of the most intricate metal projects they've ever built, Bill and his team hand make a one-of-a-kind engine bay for the '68 GTO out of steel and aluminum. Ekstensive gets its first chance to customize a 2022 Bronco Sasquatch, starting with a custom lift.

Once Bill sets his mind to something, there's no going back. The Ekstensive team strategically customizes a '23 Mustang for a world-record-breaking attempt at most donuts in a single ride. On the other side of the shop, the fabricators create a modern setup for an old-school '49 Ford truck.
