Put on a set of wilwood 6 piston brake conversion on a 71 chally, I have a set of 17" coys rims. The darn valve stem is hitting the caliper when it rolls around. Couldn't believe it. Has anyone dealt with this. I thought maybe I could get a 90 degree valve stem. Could I have the old valve stem hole welded and then add a new where it wouldn't hit? Suggestions??? Anyone have these brakes what wheels are you running on them.
