They make it easy with every single piece included. Was nice to be able to use my old steering components with this kit because I wanted to retain my manual steering. Nobody else has a set like that.

Was easy to assemble, had all the parts I needed. Only problem I have is the brake hoses are too long and they're the wrong size to adapt to the truck, would be nice if hardlines or adapters came with the kit
