M & J Restorations on Santee's Mast Boulevard handles classic car restoration and collision bodywork from a shop near Mast Park on the eastern corridor. Full-frame straightening on mid-century chassis pairs steel-gauge calipers with alignment fixtures that measure to factory datum points, a precision process that feeds into the brake and suspension re-mount workflow at Alvarez Tire on Woodside Avenue. Operating since 2008 under sole proprietorship, the facility completes projects ranging from 1949 Mercury ground-up builds to late-model Audi and Ford Ranger panel refinishing. Engine and drivetrain rebuilds during full restorations require machined components and period-correct replacements through San Diego Engine Parts on Prospect Avenue, ensuring matching-numbers integrity where the build demands it. Highest-complexity projects involve bare-metal media blasting, rust-through panel fabrication with MIG-welded patch sections, and three-stage basecoat-clearcoat refinishing applied over catalyzed epoxy primer on fully stripped frames.
