-Normal spots behind all 4 wheels on fenders and quarters
-Floor pans, especially in front of front seats up in to toe board areas
-Boxy area that surrounds the front eye on the leaf spring
Be aware that they are notorious for poor steering/front ends. Good aftermarket cures are available for whatever may ail it!
This all sounds negative, sorry. Do NOT let me scare you off. I am over 50 now and except for about a 4 year lapse, I have owned a 62-67 Nova or Acadian ever since I got my driver's license. I can hardly imagine not owning one of these cars!

Because Acadian trim, emblems, interior, etc... are not being reproduced, I'd try to find a car with as much of it's Acadian parts that are still intact. Have a look at these brochures to see what the different models look like. Click Here
Guy has a 283 with the special pan for cross member?? No drive line in it right now. I just happen to have a 283 from a 1967 chevelle available for it also.
Check the rear subframe rails, they are notorious for being rotted. They are being reproduced but require extensive repair$$$$. If you can look at the firewall on both sides, hard to see with the fenders on, but they also rot out. ARCADIAN
