[BIG BLOCK JIMMY]

Don't fall for the jeep trap. Old, real jeeps are cool but the Chrysler ones are still Chryslers no matter how much you spend. Many, many guys at work have $70K- over $100K custom jeeps and they are always in the shop. ** Disclaimer: The aforementioned is IMHO as well as those mentioned that still own, complain and continue to throw their checking account at their jeeps.
I love the old trucks we have for many reasons, but mainly because they are memory time machines. HOWEVER, I would like to build a "1972" GMC Jimmy 4x4 out of all new components. Other than the hard top, I believe all the body components are available.
If you jump in for the big win and do this and don't go bankrupt and/or get divorced, I might have to build one too. I've been drooling over the No Limits complete frame assemblys....
