My company is a distributor for FK Rodends (we are in the Industrial Automation business, pneumatics/hydraulics hence the name Fluid Power) and sell these. They are used by every motorsports team known to man and are superior quality. We stock most sizes. I can do bargin basement prices to help the car guys out. PM a part number for me to give you pricing. Let me know if I can answer any questions as well.
