A couple of weekends and a few cans of Dupli-Color ought to do'er.
Seriously, if this is a group effort you need to assign someone just to scower the Southwest salvage yards for parts, someone to do the research for technical data, a crew of metal fabricators, welders, sandblasters, mechanics, someone knowledgable in the electrical systems, hydrolics, apolstery, and one or two rocket scientist.
Man that sounds like a fun project. Oh yea, don't forget the Mack bulldog hood ornament! That should be the crowning glory when she is all done and ready to roll.
Thumbs up and best wishes, rangerj
