I have installed rear shoulder belts in my 60 and thought I would post my technique as it differs from this one posted by Jman - which I could just not do.
1. First, be absolutely sure nut plate is not there--if you cut a small hole in headliner, you should be able to stick your pinky in there to see if plate is missing.
2. You will need four nuts and two washers to fit the seat belt bolt, two scrap bolts of same size, fishing line and small weights, and some Quicksteel or other similar epoxy.
3. Cut the heads off the scrap bolts, leaving about 1" long; cover the threads with wax or some other lubricant; attach one nut to each of the two bolts, leaving about 1/2 inch of threads exposed (other two nuts will be used later).
4. Attach washers to nuts with a little bit of Quicksteel, let harden; when it's hard, make sure bolt can be removed from nut/washer/bolt combination.
5. Drop fishing line through anchor hole in pillar; remove inside panel and find weight/line. Now you are ready to attach nut/washer combo to the line (you could just wrap it around and tie it tight). Then, BEFORE DOING ANYTHING ELSE, you have to make sure you can pull nut/washer/bolt combo up through pillar so that bolt comes out of anchor hole. There are several different pathways the weight could have taken--for me, the first two times were the wrong way and I had to drop weight again.
6. Once you've been able to pull assembly up and expose the bolt through anchor hole, let it drop back down out the bottom and affix some Quicksteel to the washer--the idea being that when you pull this up and bring bolt out anchor hole, the epoxy will be in place to affix washer to inside of pillar, thus anchoring nut in place (I decided a washer was needed because I was afraid a nut alone might get pulled through steel of pillar in an accident).
7. Once you have pulled nut/washer/bolt into place, attach the two remaining nuts to the exposed bolt parts so that the whole thing can be held in place while it all sets (just thread them over the fishing line).
8. Once Quicksteel is set, take off the nut and screw the bolt out (the wax on threads should have stopped Quicksteel from binding to bolt). Attach the anchor bolt for shoulder belt and voila!
It took me several days to decide on this method, but once I came up with it, everything went like clockwork and I was done in 45 mins. Of course, Quicksteel is not the same as welded metal, so be a little ginger when tightening it up--I was able to torque it pretty good, working slowly, but I was afraid if I was too aggressive I'd pop the washer/nut combo off and would have to start all over again.
Phew. This time I'm saving this in a file 'cause I'm tired of typing it out.
Good luck!

My 60 which is an 87 did not have the nut and I could not get the nut attached with the above technique - it just kept breaking lose when I tried to torgue the bolt in.
So instead I removed the panel from the cargo area - you can very clearly see the space going up the pillar. I attached the actual bolt from the seatbelt to a short piece of thread (dental floss). With the free end of the thread I tied a small loop. Then I took a close hanger, straightened it out and fashioned a small hook on the end. I used the hanger to push the bolt up the pillar -(by going thru the rear cargo area, there is plenty of room for this big bolt - I had previously tried -unsuccessfully - to fish the bolt up thru the small access area that Jman used) and then hooked the thread and pulled the bolt thru the hole in the pillar.
Then I put on the fat washer from the seatbelt harness with some superglue and pulled the bolt tight against the inside pillar.
Now you can put on the rest of the seatbelt apparatus holding the fat washer with some needle-nose pliers so you can torque the bolt as tight as you want.
So the end result is the bolt/nut combination is backward - but essentially the same as for those who already have the nut in place.
This worked better for me - I can post some pics if anyone is interested.
