Front floor support removal and installation

There are 52 spot welds holding the floor support to the car. I know this because I used the factory weld and sealant manual to figure out the location and quantity of spot welds that were holding all this together. If you're doing any type of metal replacement on a car like this, I cannot overstate how handy this is. I'm a big fan of RTFM [Reading The Factory Manual ;) ]. Most of the major parts houses carry these. I have the whole set. In this manual, Ford is telling you exactly how they put this car together. In almost every case, if this manual says there are 10 spot welds holding piece A to piece B, I found 10 spot welds, and placed more or less as per the manual. $20 to make my life easier? Take my money!
The last 2 welds are inside the floor support. Here's the outline for the access hole in the floor so I can cut the transmission tunnel brace welds from the floor support.
Zing! A new hold in the floor. You can't see the ground because what you're looking at is the inside of the floor support and the transmission tunnel brace. This hole actually has to be larger to get the welding gun in there later on.
