Brief Description: Replaced Platenuts with Dimpled Platenut
I ended up drilling out all of the rivets holding the incorrect platenuts on and then riveting on the dimpled platenuts. This took some time but went fairly smooth. I really didn't bugger up any of the holes - the rivet removal tool from Avery's worked great!
