Pontiac Catalina 1977-1990 Vertical Lambo Doors

Start with what this kit is mechanically: a lambo door hinge conversion from Vertical Doors, Inc. that lets the doors on a 1977-1990 Pontiac Catalina swing up vertically instead of out. The hinges mount to the Catalina’s factory bolt pattern, so it installs as a direct bolt-on under part number VDCPONCAT7790, and the whole conversion is reversible any time you want the car back to stock. Here is what ships in the box:

• 2 Vertical Doors, Inc. lambo door hinges, one for each side of the car
• 2 gas shocks to support the doors in the open position
• All the mounting hardware for the conversion

The hardware is made in the USA from domestic hardened steel, and the hinge design is patented. Fitment covers all trim models of the Catalina across the 1977-1990 range, and VDI prototypes each kit on the vehicle it is built for, so the geometry is specific to this body rather than a universal hinge bent to fit. A printed instruction manual comes with every kit and free tech support is available by phone or email. A mechanically inclined owner with basic tools can manage it, but door alignment is exacting work, so we recommend having a professional installer do the job using the instructions supplied with the kit.
