60's Dart Field Find Question

You said budget isnt a concern, BUT compare Tads 65 and the one in the field. Even if Tads was $2400, you are still WAAAYYY ahead vs buying the $400 one. $2000 can get eaten up QUICK in body/welding, etc. And $2k is less than 40 hours of shop labor. Unless you can do the welding and LOVE to lol.
Spend the extra $$ on something solid.
Good luck and welcome aboard.
