We are saying the same thing Brian, I'm suggesting putting the front sub-frame in loosely, putting the rad support loosely, squaring everything off to the body, loosely. He needs the rads support to give him inner fender support to give him front wheel well support so he can cross measure a hood opening...Correct? That's also why I mentioned in my last post about readjusting his front sub-frame while he's aligning sheet metal.
I think it's the same thing as what your saying, from now on he only needs a tape measure for is cross measuring his hood opening, everything is eyeballing and splitting the best difference.
Does this make sense , if not, please let me know because that's the way I would tackle it.
