I would ask, "Why would you want to?" But, wont work, BECAUSE theres crease lines and lower "character lines" that wont mate up when you get back to the 1/4s. Theres just enough shit changed all the way around to keep anything like this from happening. Trust me, I was ALL over the idea of changing out the sick shit ass end to a "Gen 1" rear, but it cant work for the same reasons.
As far as the interior, could possibly work, but I can tell you it WILL be a PITA, because theres more than just the obvious hard parts that need to be changed.
