Yes, you've read correctly, its a Hunter F series alignment machine, with "C" series head mounting units. This uses a string for the toe in rear, hasn't been used a few years. It went into self check ok, does not have data for any vehicle in head, you have manually add info into the computer unit. The heads have no bottom feet to set into rim, used nuts and bolts with vacuum caps to prevent scratches to rims... Cannot find turntables for unit, so selling as parts unit that if you are smart can make it fully functional. Priced very cheap at $150, you must pick it up. No space to set it up. The cables alone are worth this and has updated head adapters if need. I'm the seller.
