Coming along nicely! Too bad about the bubbly decals. Can you get another set?
I also built a Goeske road runner a number of years ago. Did not like the resin body so I got a Johan glue bomb and it worked out well.
I used my magazine collection for reference only to find that the colors in old magazines did not translate well. I realized, years after the build that the chassis was actually red and the body was Omaha Orange.
When you get around to the windshield, do not cut an opening . Goeske's windshield did not have one.
I have some reference photos here: http://public.fotki.com/announcerguy/funny-cars/fearless_fred_goeske/
if you'd like to see them.
