lookn good, i'd do like maztang suggested & fill in the body line @ the taillights, makes for a much cleaner look....
i did kinda like the old paint job though, brought back some memories, it had that oldskool touch to it! what kinda paint scheme are you gonna go with now?
body filler in this are could possibly crack. Funny with the other lead post - this is what I was thinking of using to fill in this gap. will just weld it up now I guess.
still need good ventilation while welding too, the fumes from it can be harmfull depending on what kind of metal your welding, & if it has any kind of coating (galvanization, zinc, etc, etc.)
