I've been told that the rear floor pans are very difficult to get in and once they're in, you really can't get them out. So wanted to get everything prepped. I had previously deburred and primed them so just needed to get them dimpled and install the nut plates. Use the DRDT to dimple everything and then even used it to rivet the nut plates. A little bit of trial and error but I found as long as I could keep the assembly level, and if I preinstalled all the screws, I could set pretty flush rivets. Came out good.

Once the floor pan is in, they do have you match drill the spar. I won't have a lot of opportunity to deburr these holes (wouldn't have good access even if I could remove the floor pan) so I will drill the holes undersized and ream them to #30.

Can't install these floor parts s until I have the AC, but they're ready at least.
