What wheel type?

No flogging please Should I do caps and whitewalls or another aftermarket wheel ? the rest of the car is pretty stock appearing

 

Steelies with white walls!!!

 

I'd do the same thing you have on your Plymouth...

 

Skinny 15 inch steel wheels, Tall bias ply whitewalls, Classy Sombrero style hubcaps. No flippers or ribbed caps.
Radial whitewalls if you don't care about the look and want better ride quality.

 

I was tossing 57 cad caps overdone?
