[68Timber]

I've got Pro Comp series 97 wheels on my 85 Blazer, 15x10 wheels with 3.75" back spacing. They've been on the truck almost three years now, no problems. The rod ends are close to the inner lip like yours but I can get a fingertip in-between them. Your tire shop is being a little too picky. I'm on my second set of tires since installing the wheels and neither tire shop squawked about the rod end clearance.
