Another one of those, "sure wish I had the right tools" jobs. Not worth the drive home to get em so it took 2 hours to install 3 nutplates with flox and UNI over the job. I couldn't justify riveting them in from inside the hell hole so I floxed em in just like I did on other bolts where the head was floxed in. Shouldn't be a problem at all. This is one of those final, "cramped place" jobs to be done so it's all smiles going forward :)
