These new rims have the nubs to hold on your wheel covers. They are also manufactured so they can be used with tubeless tires and have extra back clearance for use with single piston disc brakes.
We suggest you fit your hubcaps to these wheels before you paint and finish. There are several reproduction hubcaps on the market and original hubcaps vary. You may have to grind down the nub that holds on the cover for proper fit. Use a rubber mallet to install your hubcaps, make sure they fittight so you don't lose any.
If you are using full-size hubcaps you will need to use long valve stem set #642108 if not then you will need the short set #642119.
These wheels are 5" and use the full hubcap. The 5-1/2" wheel was designed for use with the RPO "Dog Dish" hubcaps.
