Centerline Smoothie Problem

[drasticwagon]

I Have them on my 65 and on my 67. I battled Centerline for the longest on the center caps for the front and gave up. I have a mess load of center caps that they sent me thru out a 7 month period that will not work. I know I might be able to go with the bigger style cap rather than the rounded at the top cap , seen it on a few. I'm not sure that my wheel will fit them though. Has anyone found a smaller hub or grinded it down a little before? Just curious , I gave up for a while but now I want to fix the problem again.
Thanks for the help....
