wheel clamp for alignment

as a note to others...IF you can locate the Hunter tech rep through say your alignment shop, you may be able to buy these adapters reasonable from him. Many wheel sizes are now hovering the 20" and up range and so they need to be always upgrading equipment. Many of us will never install wheels this large (hopefully) on the cars of the era this forum caters. The above adapters are good from 10" through 18" diameter...I will first use them on a set of 12 inch wheels on an English car I just put new R&P boots on. At this time my largest wheel on my more modern vehicles max out at 18". They do make extenders for this model to extend the range of wheel diameter..so not see a need for this at this time however.
