I can't confirm other models or years but I even after disassembling and cleaning the front seat belts in my 88 BJ74. I was disappointed in their performance and wondered how they might perform in the event of an accident.
I ended up purchasing a set of black seatbelts for a 2007-2016 79 series based on a few pics I saw in other threads. I was expecting the possiblity of some trimming to be necessary. Instead they were a direct bolt in fit. I now have brand new seatbelts in the front seat that feel much more secure. Now to figure out a better back seat and seatbelt option
73210-60663-C0 (RH)
73220-60523-C0 (LH)
Also I did not replace the receivers but they click together just fine with the originals
