Did you rivet or rivnut the floor? Main reason I ask is you'll probably want to rivnut the passenger side kickplate and the bottom holes can be a pain to drill out and rivnut without your floor paint taking an L - there just isn't enough room for the tools as well as have a straight shot at the holes. Also, wait to actually install the kickplate until after yo have your front control arms and steering rack torqued down.
If you've rivnut the floor you can unscrew just the front > rivnut kickplate and bolt back in cleanly.
edit; I sweat that garage!
