Hub caps?

I bought few months ago a few hub cabs for El Camino. Those are from 50's Chevrolet and not in a good shape. As I currently have just plain steel wheels with some red paint on them(from previous owner of the wheels) those match quite good on the habitus of El Camino. But I have been looking for a hub cabs since I bought these wheels.

These are physical in good shape but not in aesthetically. So, those need TLC and I need to figure how to attach them securely on the wheels.

Here is one inserted as mocked up how they look at wheels. Any suggestions how to attach these securely on the wheels? 

Numbers of the year!

56899 miles.

The year is ending and El Camino isn't moving anymore this year, so it's time to see what and how far we rolled this year. Out of the garage in April and back to (different) garage in November. So that 7 months of driving around and we rolled 3614.3 miles(5816.7 km). A bit over 500 miles per month, not bad as we didn't take any longer trips this year. Last year we did trip to Northern Finland and rolled 1300 miles on a single trip and month! 

Average mileage is around 18 litres per 100 km. A increase from last year's ~17 l/100km. I bought a new tires with wheels last year and had to install them under El Camino in September. Originals were 14" wheels and I'm not sure were those tires 215/60 or 205/65, The new set was 15" wheels with 215/70 and we drove with the new tires only two months so it didn't affect that much on last year's mileage, but I hoped it would show in this year, but no. Okay, we had more in city drives than longer drives so that is a one reason why mileage increased. One thing that should help getting lower mileage is installing a insulator between manifold and carburetor, by lowering carburetor heat energy and thus eliminating excess fuel vaporation in carburetor.
