PETERBILT 379 YEAR 1999 DAY CAB CONVERSION KIT FOR PETERBILT UNIBILT Replacement Body Panel

This Peterbilt Unibilt Fatback 6in Day Cab Conversion Kit is a pre-assembled fiberglass panel solution designed to convert Peterbilt Unibilt sleeper trucks into functional day cabs. Specifically engineered for 1999 Peterbilt 379 models and compatible with Unibilt non-integral sleeper configurations including 359, 377, 378, 386, and 389 models, this kit streamlines the conversion process for fleet operators and owner-operators seeking to repurpose sleeper units. The kit features a 6-inch Fatback-style extension with a 17in x 32in window for improved visibility and cab comfort. Construction includes pre-assembled CNC-cut and pre-drilled fiberglass panels with Class A gel coat finish, eliminating extensive fabrication work. All components arrive with pre-installed sound deadening core for noise reduction, complete upholstery, and necessary hardware and sealers for quick installation using standard rivets. This conversion kit is ideal for trucking operations looking to maximize equipment utility, reduce idle sleeper cabs, or transition vehicles to dedicated day haul applications. The pre-engineered design minimizes installation time compared to custom fabrication while maintaining professional appearance and structural integrity. Compatibility is model-specific. Ensure your truck uses Unibilt, non-Unibilt, or Ultracab configuration before ordering, as kits are not interchangeable. Complete all measurements and truck specifications prior to purchase.
