As noted in the wiki, 230s up to 006055 had two-point shoulder belts fastened at the top of the B pillar and to transverse beam.
I am attempting to find correct belts for my car 000133. Were they Kangols? Does anyone have any pictures or memories of these early belts? Or better yet, the belts themselves because they were upgraded? The PN is 113 860 04 85.
Thanks,
