Floorpan cross tube thingies, Best way to cut them out? Options

[campbellcj]

I finally made some more progress on the car this weekend -- finished the engine compartment side of the fuel line and Weber fuel bar replacement, redid the rear f/g bumper mountings (dzus) and pulled the seat to begin a bunch of interior stuff.

To mount my new seats, I will need to channel or completely remove the box section that goes across the floor pans (i.e. approx. under your knees). The seats will be on alloy sidemounts that are bolted directly to the floor, which I'll reinforce a bit.

Question is, should I hunt down a plasma cutter or cutting torch (i.e. pay a shop) or can this be done decently with what I've got, i.e. just about anything else (cutoffs, grinders, drills, etc)??? (IMG:style_emoticons/default/confused24.gif) I don't want to butcher the floors as they're fairly clean and I don't have a welder, either. (IMG:style_emoticons/default/unsure.gif)

Thanks again 914 gurus! (IMG:style_emoticons/default/pray.gif)

Thanks guys...I was starting to think that just notching them would be the "way to go". They do appear to be spot welded but a LOT of spots! Plus I figure the remaining metal will add some degree of stiffness to the floors.

I'll try notching, folding forward and then cutting/grinding off the excess sheet metal.
