First, let’s see a full picture of that gorgeous 68. The wheels can make a break a car. Sometimes the OE or another version of OE is the best way to go. In my opinion, you don’t wanna make the car look like something she’s not.
Why are you looking to get away from What’s on the car now?, what look at you going for?
I too have the Road Wheels on my 77, had considered at one time going with spokes or a type of wheel that expressed a touch of class, but then realized the road wheels did exactly that. Just my 2 Cents.
