Josh,
I don't know if this wil be helpful or not. Are the tabs drilled with pilot holes, or is the center hole full size for a camloc? If pilot hole drilled, I would suggest Nutserts. They are available from ACS. You will need the "disposable" tool. What I do when inserting them is chuck the cap screw in my cordless drill and with the tool in a box wrench spin the cap screw to set the nutsert in place. If you use the allen wrench, eventually it will wear and slip. My disposable tool is years old. It is only the cap screw that needs replacing from time to time.I have used them extensively on lots of projects. I prefer them to rivnuts because they are steel vs. aluminum.
The tabs for the seat are setup and pre-drilled... You can use nutplates, nutserts or use hardware. The tabs can be reached by hand to put nuts on. The hardware makes removal and installation a little more difficult.. the nutserts ar a good choice but can slip over time.. again, you can get to them by hand so if they did slip they would not be hard to fix. The nutplates will require you to drill new holes.. or enlarge the holes.
In the age of the Internet a picture is still worth a 1000 words.

I am thinking of going with rivnuts. I was going to use nutplates but the holes are about 1/8" too far apart. I have never used rivnuts. Does anybody have any recommendations for the rivnut puller and for notching?
I've used the Harbor Freight 3 in 1 rivet puller to set rivnuts for my tail access cover. http://www.harborfreight.com/3-in-1-...kit-94100.html
It did the job without breaking the bank. I'm not sure about the notching you mentioned.

I was under the impression you put a small notch in the material you are adding the rivnut to about a 1/4 of the diameter of the rivnut so that it resists rotating.
I used nutplates. I believe they are more secure than rivnuts. Yes the two rivet holes in the weld tab are too far apart, but I don't think they are as bad as 1/8". Using the nutplate as a drill guide I just egged out the holes a little until the rivets went in just fine. The two rivets in a nutplate only serve to keep the plate from rotating while you tighten the screw, so I wouldn't worry much about some slightly egged out holes in a non-critical spot like the seat. The old way was to use zip ties!

I didn't notch mine and they haven't spun. Guess I'd like the answer on the notching tool too.

This guy has a nifty tool for notching.
