I presume its a Challenger correct?
If it is, an acquaintance of mine had one down to about 3000 Lbs in wet street trim but he had a very good set of fiberglass fenders and hood as part of the tricks that looked like their steel counterparts. It had a patina on it that made it look rusty and no one noticed till I caught a hint of it one time. An artists eye never lies.
We kept it secret for a while as he was test and tuning with good numbers for a street driven E-body.
