Unilug wheels
 

I have a chance to replace my 8" keystone classics (cant buy them anymore ) from someone who has nos unilug that fit a 1965 442 olds will they fit my 70 mustang? looks like bolt patern on my car is 4 1/4 but I am not sure. Any help appreciated
Thanks
Jon

Unilugs are slotted to fit all 5 lug hubs. I have unilug Cragar Super Sports on my 65, all you need is the correct type of lug nuts, which go through the slots to center the wheel on the hub.
They are a pain in the butt to mount, but they should fit.

Bolt circle measurement. For five bolt, see: http://www.wheelvintiques.com/measure.html

Yours should be 4.5"
