I got these set of Magnum 500 15x8" from Mustangs Unlimited and need to install a set of beauty rings on them ( I know they don't come with them) they have rusted quite a bit in the outside edge and also on the joint of the center piece and outer rim. I tried some corvette trim rings but they don't go in all the way and about 1/2" sticks out. Has anyone tried to fit a set of trim rings in these wheels and obtained a good fitting? I will like to know who sells them or where to get them. Thanks.
