67 c10 wheel questions. -plz help.

[Ajb8510]

Hello,
I recently purchased my 67 c10, and i like it alot,
But i'm wanting wider tires on the back.
The problem i'm having is that i want to find the same style rims for the back, only deeper, and i cant seems to locate any.
They seem to be just stock wheels,
and normally i would just buy a whole new set,
But i just found baby moon hubcaps, and beauty rings that fit the rims that are on there, and so i would need the new wider wheels to fit the hubcaps, and rings too. does that make sense? lol
Any help would be greatly appreciated, i'm sure they make them, i think im just not looking in the right places.
