68 Plymouth hubcap question
This shows your options on a 68 Barracuda (not shown are the small dog dish caps that were standard). Wheels were 14s not 15s.

Below are pics of the wire covers and small caps that I use on my car (note. With the small caps the wheels should be body color and without trim rings)…… I also have the wheel covers posted by Matthon in post #3.
