The rear suspension is the CalTrac system with the CalTrac mono leaf spring. It sits just right, and it is glued to the pavement when hammered (the RR has a 660hp 505ci Hemi, A&A racing 727, and Dana w/4.10s).
I don't know why CalTracs work but they certainly do. Everyone I've met or read about that has CalTrac on a B-Body says the same: it glues the tires to the ground.
The paint was done in Indianapolis by Goverts Paint. Total Mopar family heritage, as Wayne Govert is Ray Nichels son-in-law. I understand from the previous owner that it was truly the original formula of Chrysler/ PPG High Impact "V2" paint, but using modern chemicals and lots of clear coats.
I live outside Sonora, up in the Mother Lode. I make the Sacramento and Madera shows each year, (great shows) but I missed Mopar Alley each time. It's on my schedule for this June. It'll be great to meet you and forum members.
