Cut it, I did... my RS/SS #'s matching.. I know, I know.. why? I am convinced it's my car!,(thank's to several heads here on lat-g) I have had it for bout 11 years now. Its not going anywhere. I'm not selling it. I considered selling it, only cuz I was bored with it.
However, I did have an inconsiderate butcher it.

Kills me to know It went to an inexperienced "plastic surgeon". Its been down now for 2 plus years. Mind you this was a running, all original, car show quality car, before I decided to cut it. It did have some bad rust issues that were covered up and had to be fixed.
Its getting fixed now, properly, but it did set me back at least a year and am glad I did decide to Mini-tub it.
So.. go for it. You'll enjoy the car all the more!.
