Looking at the 50+ YO passenger seat's belt in my old car and wondering if it's "safe" at this point. The shoulder strap is long gone since it wasn't reinstalled after the headliner was replaced before the roll bar was put in... now it's just a factory '73 lap belt.

Since I need to get an updated 5-point for the driver's seat, I'm wondering if I should get a second harness and add one for the passenger. I'm interested in what approach others have taken. Thx
