How many of these do you need to move a car ? it looks like they should be sold as a pair

I have sold a few sets these in the past in pairs and all people asked me is can i sell them a single Jak! This is why i listed them as singles because some people don't require pairs all the time! There are two listed on e-bay so should you require a pair you can bid on both! Good luck should you decide to!
