I have just 1 hubcap for a Dodge Dually truck. I'm pretty sure it is for the front wheel.
Probably fits years 94-02

Make sure the cap in the photo looks exactly like the cap you are looking for.

I can e-mail the photo, if that link doesn't work.

How about $16.00 plus actual shipping cost ?

E-mail me , if interested

Thanks,

Rob
