That would be the ultimate thing to do is get a good frame and work from the ground up. But IMO you would need some sort of a base or donor jeep. You will find out that you dont want to find every single little part #1, and #2 that you you dont want to pay for every single little part. I am planning on purchasing an additonal 91 or newer jeep to do just that build from the ground up.
what ever you choose good luck and it will be fun. Jeeps are fairly simple to work on all you need is a lot of ambition. And the abilty to read and comphrend.
