Watched this thread for a while, let me offer my thoughts for whatever they're worth...:smile:
Of course we all know there were some 20,000 GN's produced in the final year (versus 547 X's). So one would think that cloning a GN (i.e. losing/modding an original one) is no big deal, right?
Nope. Let me tell you why I disagree-- despite the higher production figures, those GN's are really starting to climb in price on their own and the following of fans and collectors is only going to grow in the future. These are great cars and you're seeing fewer every year (though the survival curve will start to invert soon, I'm sure)!
Bear with me while I offer you a simple comparison-- let's consider a Hemicuda (the X) versus a 440 Six Pack Cuda (the GN). Both are quite desirable, perform very well, but one's worth more than the other, of course.
BUT-- Who in their right mind would alter or chew up a genuine 440+6 Cuda just to make a Hemi clone? And that clone would actually have less value than an original 440+6 car (this is objectively provable). It's the same with our cars-- despite the fact that most of these changes are bolt-on (except cutting the front fenders, some artifacts of wheel flare installation, cutting up / rewiring the dash innards, etc.), the cloned GNX's (with changed out suspension, altered trunk tags in some cases, etc.) are worth LESS to most collectors than an original GN in the same condition. I believe this will be even more true in the future. Plus, most people don't even attempt to go the final mile and do the real dash with the proper gauges (or can't afford the money, time, engineering degree, headaches, etc. to get it right). Or maybe they give up and throw in a set of VDO's instead. Same situation with the suspensions (though you indicated you have one already).
So what happens? Most will end up with an incomplete, half-a$$ed hybrid orphan clone that'd have been better left as it was born. This is the worst of all worlds, but an all too common scenario that has befallen some of these great cars-- ones that still stand tall after 20 years.
So if you want to truly clone an X, go all the way but do like they do with the Slant 6 and 318 Mopars (in our world, consider the challenge of grandma's NA V6 or 307 Regal instead) and do the X thing to one of THOSE if you must.
Just don't chew up a real, genuine GN (or Regal Turbo, which is even rarer) to do it!
