I have those wheels as well. Size is 17x8 and 18x11.5. I had the standard 11” barrel widened by 1/2” to allow for more tire options (295/35/18, 315/30/18, 335/30/18). At the time I purchased my Boyd wheels from American Republic Wheels which are not associated with Boyd wheels now if I remember correctly. If you contact Boyd I would tell them what you are looking for. When I had ordered my wheels I told them I wanted a stepped rim and a center accepts the Detomaso center caps. Pantera East did a nice job with these wheels.
