Established in 1999, Autoworks Parts in Santee is an exclusive classic Ford Mustang restoration and restomod parts supplier operating from Prospect Avenue in the 92071 industrial corridor. The shop manufactures proprietary bolt-in power door lock kits and wheel tub panels for frame-off restorations, supplying the same Woodside Avenue corridor where 1904 Customs handles custom body fabrication. Coupe-to-fastback conversion packages transform 1964½–1970 Mustang hardtop shells into fastback profiles using factory-matched stamped-steel quarter panels and rocker extensions. Widebody builds require precise wheel backspacing and offset calculations, a fitment process the shop coordinates with Budget Tire Co of Santee for competition-grade wheel-and-tire packages on the same Prospect Avenue block. Full restomod assemblies integrate modern drivetrains, independent rear suspensions, and electronic fuel injection conversions into stock-appearing 1964½–1970 Mustang bodies using the shop's proprietary body reconditioning process.
