It alledgedly is mopars performance ignition box. My 2 YO orange box took a dump 3 years ago and I replaced it with a standard box and haven't noticed a bit of difference except it works. My A-body has a MSD.
A buddy of mine had his stereo installed in his Duster by a professional store who put it in a nice surround and mounted under the dash in the center. It looks nice.
Maybe check and see see what a stereo shop has to offer.
