I think it might be wise to build a jig from a couple big I-beams,or something similar that would allow you a real heavy,stable jig to keep that car squared up and keep it from moving around all over the place while you're trying to cut and weld on it. It would also pay to spend some time giving serious thought to what your overall plan is.It seems like you're kinda winging it here.Maybe just take a couple weeks,go through some AWB picture threads on the Hamb,and some on other sites,like George Klass's,then you can have some really solid ideas of exactly what you like,and have a pretty solid road map of how to proceed. It'll make your life easier,save you from doing things 2 or 3 times cause they weren't right the first time,and the car will be built to a higher level of quality and safety the first time around. Also money well spent,would be a catalog from a company that supplies early Nova sheet metal like partial floors,rockers,etc.Getting the car as solid as you can before you move forward with any more fabrication might be money and time well spent.As soon as you put any weight on those front frame stubs,they're gonna flex all over the place in you,and you'll never be able to keep anything square. Chasing your tail because of stuff like that will turn you off a project real quick. A little bit of time spent prepping for the work ahead of you will be well spent.
