I'm 48 and have been building since I was about 7 or 8 my older brother who would be 58 if he were still with us got me started, And I usely put something I know he would like or a part of a model he built that I broke into almost every thing I build, ie the Short bed chopped 57 Ranchero I finished last month has the Intake,Carbs and air cleaner from his AMT 56 Ford.
