[lime73]

I am replacing driver side floor pan on the cuda and would like to know how far apart i should place the spot welds on the crossmember and down the rocker side. any input would be great.

did you remove the old one? if you did you shoulda made note of the placement.
is the passenger side still in? you could use that for referance.
just thinkin out loud.

  Double what was used from original, unless you can do a better job than was done at the factory. Remember the factory only did what they had to because of costs and the time on the assembly line.
  Our E bodies are not that ridgid that is why frame connectors & plates are regulary fitted to strengthen the whole car.
