NOS Klippan seat belt assembly for the R107 350 + 450SL/ SLC
I have two boxes with 1078603385+ 3485 but the assemblies are the same and not left and right.

Doesn’t get any better than this with a date code of 1973 and if you’re doing a restoration the most important thing is the safety of the occupants. Don’t rely on tattered belts.

Will probably fit the W114 280C and other models.
