Scout II Floor Pans (welding)

[acman]

So I purchased new floor pans for my 74 Scout II, I am wondering what is the best way to fit them up?

Should I make a butt weld on the long seam? I have a guy to tig it and he is a great welder. I know the fit up would be critical to make the butt weld. Any thought here?
I have the passenger side cut out already, and I left about 4" from the original seam.(front to back)
I figure we would spot weld the rest of the pan down to the existing body as it was originally installed.
I also bought some weld thru primer to spray on before we weld.
Any feedback is appreciated.

Pans can be done a few different ways but imho, flange welds make a stronger seam due to having 2 pieces together. You have less chance of burn through than with a butt weld.
Flange tools are available at hf relatively cheap.
The panels can be butt welded with ease, cause the Scout is made outta real metal,cut out is critical as you said. Cut the hole small and work your way out.
Weld trough works great, love the stuff, its just not permanent, make sure you, at least put some kinda self etching primer on the underside, then undercoat the hell out of it.
Im not sure how the replacement panels are made, if they have the seam flange on them, id take it all the way to the seam. If not then leave the seam and cut it in.
