what would it really take?

Hey lvchris. Welcome to FABO from SoCal. You're going to have fun here.
I suggest you and your son, and the rest of the family too, come on out to the "Moparty At The Strip" at Las Vegas Raceway in mid-April. You'll get a chance to see one of the biggest all-Mopar events in the west with both a great show field and drag racing. You'll also get a chance to visit with any number of vendors to see what's available on the aftermarket and what prices are like.
If you get a chance, and you get there before noon on Friday or Saturday, look me up and say "hi". My club, Inland Mopars (from SoCal) will be parking the show field cars. My wife and I will be parking the A-bodies so we'll be easy to find.
I hope you get a chance to get out to the Moparty - it's a great event and you'll get a ton of ideas for your build.
