n most cases hardly anyone ever gets to see the foundation of a great build—and we mean the chassis, how it was assembled, what components are used, how some engineering feat was accomplished, and generally how a builder (at home or in a shop) was able to pull it all together. Once the body and bed get dropped on top of it, no one will get to see all the workmanship and creativity that went into it.

That’s why we’re happy to showcase this particular chassis because, besides checking all those boxes, it’s a spectacular piece of rolling art in its own right. Well-known slammed truck owner Tony Leal is having Old Anvil Speed Shop (Orange, California) go through his ’68 International Harvester Travelette. The body and bed is about to be bolted down, so we thought it would be a good time to get some photos of what lies beneath.

Paul Bosserman, chief designer and fabricator at his Old Anvil facility, went all-out on the scratch-built 3×6-inch chassis (powdercoated in a custom color by Americoat), adding his own touch to an Air Lift Performance bag suspension for both the IFS front and four-link rear. A Ford 9-inch rear was also utilized and fitted with 12-inch outboard Wilwood disc brakes (the same setup used up front) as well as 20-inch Weld Racing wheels on each corner.

For power, a direct-injection 5.3L (325-inch) L83 motor is backed to a 6L80E trans and is fed by a Holley Pro-Flo fuel system. Old Anvil made the fuel tank and topped it with one of their own filler neck ’n’ cap combos. Other Old Anvil products are also located throughout the frame (which uses hidden internal routing for the wiring, brake, air, and fuel lines), including CNC-milled -6 and -8 bulkheads to connect the hidden lines to their intended part along with -3 bulkheads for the brakes and 0.25-inch NPT fittings for the air line.

Old Anvil Speed Shop recently had a very busy weekend at the 2023 Grand National Roadster Show in Pomona, California, as they showcased this finished International Harvester crewcab along with a Ford crewcab, a Rambler race car, and some other vehicles, and they’re working on more to debut this coming year.
