Have a classic car with a bench that only has a lap belt.
Instead of replacing the whole belt system (newer 3 point seat belt), are there any options to install just the upper body restraint, in addition to what is already there? Or is this a sloppy solution?
Weasco sells retro fit belts with detailed instruction for 3 point belts http://www.wescoperformance.com/retrofit-seat-belts-shoulder-mt-door.html They include models for convertables and sedans. You can select just the shoulder belt add on or a new complete belt system.
