Full caps on your wagon, though in most cases I would choose dog dishes. I don't thing you can make a wrong choice here.
Nice wagon, my granddad had one like it, only it was black. If your asking for opinions of the two choices. I like them both. The full cap makes me think it may have been a more optioned car. But I'm a Hot Rodder. So the first thing I did to my grandad's, was to pull off the caps. lol If it were mine, I'd proabably put on some chrome reverse, or gray spoked Americans. I just never liked stock. But it's your car , so you need to choose. I'd flip a coin??? Wagons are now COOL ! We love our 56 Nomad. Ron....
What's the plans for the car? Looks to be stock as a rock. I guess I would leave full caps on it. May be lower it and the do something different with the wheels.
If the wheels were black I'd say full caps, but that is a pretty color and look good matched to body color
Dogs & trim rings. Is there Vette full cover you like & same diameter? I'm mostly a ford guy, but, I LOVE your wagon!!!!
You have full caps on the passenger side and dog dish on the drivers side, just switch them around ever now and then and it will look like a different car! HRP
