I have been searching for at least a year for rear seatbelts (the male ends that bolt to the floor) and I have had zero luck. No junk yard has them, noone on craigslist will part with them, nearly everyone who said they would sell me a set never came through. I dont like to "rig" something up, especially something like seatbelts, but I am facing the music that I wont find anything factory. So what I am asking is if you bought aftermarket seatbelts can you post specifically what you bought and how you installed it? Obviously safety is my biggest concern as my kids are who will be riding in the back. I am not a fabricator and so it needs to be bolt in basically. I dont have the cash to swap in a new bench seat with built in belts right now. My truck is a 1990 k5 and it appeared to have 3 point belts but I will settle for 2 or 3 point just need something FINAL. So lets see what you bought. (part numbers are bonus points)
something like this maybe?
