Seat Belt Fitment Resources for Classic Cars & Trucks
We've updated our seat belt fitment resources to make it easier to choose, measure, and install the right seat belt system for your classic vehicle. Use the guides below to compare belt types, review mounting requirements, and determine the best solution for your application.
RetroBelt seat belt systems are designed primarily for classic cars and trucks from model years 1975 and earlier. Because every vehicle is different, proper fitment depends on available mounting points, interior configuration, and the type of restraint system being installed.

Important Fitment Reminder
Universal seat belts do not install the same way in every classic vehicle. Before ordering, review available mounting points, seat position, interior clearance, and vehicle structure.
If your vehicle does not have factory seat belt anchor locations, additional reinforcement hardware may be required. Custom installations should be performed by a qualified professional.
