Are the older Mopars bodies with a frame easier to restore than the newer unibody cars? Back some years ago, I knew an old timer who had restored a number of cars. He refused to restore any unibody cars. He claimed cars with a frame were easier to restore. Any truth to this belief?

(I'm not real concerned about the drivetrain restoration. If I were to tackle an older car, I'd probably update the drivetrain.)
