I'd like to see a photo of that on a 69-up-style 15x8 Magnum wheel; I'm thinking about 15x8s on a '69 B-body. Not sure if they'd hide the outer part of the recessed areas. Many years back, I ran something like the Vette rings on 15x8 Rallyes on a '70 Barracuda, but obviously they're not brushed. Further back than that, I put 14x7 Magnums with Ford 14x7 brushed trim rings on a '69 Road Runner and it fooled pretty much everybody. Those rings were discontinued years ago, and I'm kinda hung up on stock-appearing 15x8s for those cars now. I'd prefer to avoid the '67-'68 full chrome Magnums on '69-up cars, and I didn't have good luck with the trim rings staying on the chrome barrels back in the 14x7 days.
The 15x8 Magnum wheels with painted barrels ('68-up style) are available from Coker, but they're vague on the trim rings.
