Rear seatbelt install

[randall2314]

Hi all! I just bought an 81 e21 320i from my son who took out the back sear (Dont ask why?) and now I’m trying to reinstall the seatbelts and backseat. It should be easy, right? Well, I’m unable to figure out how/what goes where. I have bucket of bolts and washers and a few seatbelts (Some extra from the previous owner). Does anyone have pics or a reference to where they go and what bolts and sizes are needed for the seats and seatbelts?

Thanks in advance!
