Just my 2 cents on the wheels.
The wheels in the picture are not the ones in the description (Rallyes with Good Year Polyglass tires. F60-14). You might know that already.
The wheels look like aftermarket 15" Magnum 500s. You can even order them from Summit Racing/Jegs/Paddock/etc. for about $130+ for 15x8 rim. The pictured tires are current day Good Year radials.
If I'm not mistaken, 72+ Cudas (and Challengers) had the option of Magnum 500 rims but they were 14" non chrome only from the factory and needed a brushed aluminum trim ring. I think none came chrome for these years, although in the mid to late 60's chrome 14" Magnum 500s (no trim ring) were available as I just talked to a guy with a '68 GTX that told me this. With the 14" wheels, you can't put too much tire on them, I think the widest is 235/60R-14.
Here's a pic of mine. 14"x6", brushed steel, brushed aluminum trim ring. I think the trim rings are factory. They look like the ones the Paddock sells in thier catalog.
