You got a lot of good advice already. But if you want to do the blind nut way. I have put a wire through the hole and fed it through to where I had access. Then slipped the blind nut on and put a loop in the end of the wire. then pulled the wire back the other way till the blind nut started. Cut the wire and quickly started a screw in the blind nut so it could be seated. Then shook the plane to get the wire end out. It's not a perfect way, but it will work. This is assuming there is an opening to get access to the wire.

Bingo........... your system works. Can I offer a similar one...
Braided wire works great.
Dave's system works, but I use a wheel collar and don't have to do anything special. The smaller the collar the better but no matter the size they can easily be made to lock onto the wire. They hold so tight you can pull hard to seat the Tnut. With the nut seated, back the wire out. Run the bolt in and tighten and your wire is ready to do the next nut.
The security of a Tnut is hard to beat.
If you've got an OS engine, you've also got the perfect collar to use. They supply them and a short length of braided wire.
