Help with Tru Forged Mach 5s

I have a set of 18x11 Tru Forged mach 5s. After doing a solid axle swap in my 03 Cobra the rear tires now stick out too far. I had spoke with Steve about this a few years back and he told me my only option was to replace the outer lip rings. Things came up and i never had a chance to order them. Now that he's out of business do i have any options to narrow the wheels?

Thanks
