Cobra R rims and drum brakes...67 fastback

I am considering putting a set of 17" Cobra R type rims on my car because of problems with the old Crager rims I am having but I have drum brakes on the rear and the drums are going to show thru and I hate that look.
Does anyone have any ideas for hiding the drums or making them look a little less noticable.
I am not ready to spend the money for the rear brake conversion to discs so would appreciate any ideas.
