1904 Customs in Santee's Woodside Avenue industrial corridor specializes in custom metal fabrication and upholstery for hot rods, off-road trucks, and performance builds. On-site TIG and MIG welding produces roll cages, custom brackets, and hand-formed sheet metal panels, contributing to the same East County build pipeline where San Diego Signs & Wraps executes vehicle graphics and wrap finishing on completed projects. Interior restoration covers dash panel re-skinning, door card fabrication, and full cockpit re-trimming in leather, vinyl, and Alcantara. Complete restomod projects pair the structural metalwork with drivetrain integration and specialty hardware sourcing from Santee's Prospect Avenue auto parts corridor, which includes Autoworks Parts. Welding capabilities cover mild steel, 4130 chromoly, and aluminum sheet from 18-gauge to quarter-inch plate, paired with hand-stitched upholstery packages for show-ready or track-ready delivery.
