This is a good thread for getting the info straight on Jacks. I don't know how to tell one from the other. I've only know what came with the truck and at this point in time that wouldn't have to be the original.
I know two Jacks, but neither's name is Jack. My friend Chuck has a shop called Jack of Arts and the other friend, Pat, is Jack's 4x4 on this site. so I guess I don't actually know Jack, but I know Chuck and Pat. It's funny when I go to shows with Chuck. Everyone knows him through his shop and guys who think they know him well call him Jack
