Yeah, you can't find every part needed to build the car out of a catalog like a Ford, Chevy, or Dodge. In other words it's a much harder restoration job that bubba can't do in his back yard.
Or because most of them are not worth restoring unless they have sentimental value. Not like "bubba" can restore a 63 Corvette either. Dust the sand out man. I don't like Javelins, you do (obviously) so have fun with it and enjoy it.
