I would suggest BEFORE removal of the old braces to simply measure from the front (or rear) of the box floor and also from the edge(s).
Draw out the dimensions on a sheet of paper then use the original measurements to lay out where the holes need to be. Heck IF you used heavier wall tubing you...
I'm no expert BUT, if it was me I would wait as long as possible for the paint to dry before undercoating. That way most if not all of the solvents will evaporate out of the paint. A rule of thumb I have used is 30 days. Probably overkill but I would rather wait then possibly have drying issues...
You did the right thing (IMHO). I personally don't understand what prompts people to even THINK about cutting up a solid vehicle. It isn't like they are made any more.

Unfortunately I don't think there is enough 'slack to perform such a move.
I may be WAAAYYYY off but,
What is the coolant temp reading on the scan tool?
I ran across 3 different GM vehicles in 2 days with no codes and running rich. ALL off them had the same reading of -40° on the scan tool. (Must be the 'default'). Changed the sensors on all 3 vehicles and no more...
Yea, intermittent problems are a pain in the astrological forecast.
You could just do a simple visual inspection to see if there are any "IFFY" spots in the harness. One good place to check, though a pain in the rump roast is right at the fuel pump connector.
A friend of mine dropped the...
DON'T fire the parts cannon till you verify if it's ignition or fuel related.
Simple shadetree method is to give the engine a snort of carb cleaner when it won't start.
IF it starts then dies after the carb cleaner is burned up then I would say fuel issue. IF it don't then it's ignition...
