where did all the cool rims on muscle cars go?

and Keystone Klassics... What a cool look. I still remember the first time I noticed them, I was 6 or 7 years old

no one seems to run 10 inch rims on the back anymore, and no one seems to have slotted mags either. I loved those, and had a set on my 71 Challenger
