Had a little time yesterday to work on the "Z". I straightened up a couple places on the firewall so I'd have a straight clean edge to start rebuilding. Then I made one of the two wells the intercooler tubes will pass through. I might use this one or I may try another approach. I'd like the mating surface to be a little smoother than this one. [shrinker sorta' wrinkled it a little]. This is my first attempt at any ''real'' metal shaping so there may be a few trial & error attempts on this deal.
