Ive got a MIG unit at the house I use to weld up SFC's for people with. It welds fairly clean as long as the metal is clean to weld to.

you will be fine to weld it with that machine as long as it is capable of welding the thickness of metal you are working with.

Yeah, we'll, I will be taking my sweet-*** time prepping the areas that are going to be welded, it should turn out ok. If I have any doubts, I'll be getting ahold of you V6 Bird.

You don't have to use a shielding gas with flux core. The flux in the core burns off and shields the puddle. That is a lot of the reason splatter is so bad with it. If you have a true MIG and not just a wire feed welder, I can't imagine any reason not to use the appropriate solid mig wire.
That said, if you only have a wire feed welder and can stand the splatter (I pity you if you are going to do this laying on the garage floor ), flux will work fine. A lot of small commercial welders are actually rated to a slightly thicker material with flux than with MIG.

i've used a flux core welder with ok results. granted they are not the quality of a mig welder and not ever close to the quality of my tig but they are fine for general welding.

One trick I found is to clean the metal with a wirewheel then weld with good heat and penetration, but once you stop reclean the metal again. So if you weld two inches and stop, clean only take you a couple of seconds. You will be amazed. or get a gas conversion for about $100, it will be money well spent. Youll wounder how you lived without it and never go back to selfsheilding wire.

I think I would try arc welding them with a 3/32" rod. I HATE welding under a car, but that might just be because of my average welding ability. Best case would be to flip the car upside down and weld them on.
Shield gas with solid wire ftw.
