Both r.d. enterprises (stainless steel copies of the original hinges) and Banks (brass hinge kit of a completely different design) hinge kits contain only hinge bits. The assumption is that the bobbins in the body and the door are in good shape. In fact, the hinges I got from Banks assumed that my body bobbins were worn and the pin part that sits in the body bobbins was too thick so I had to have them turned down a bit so if you get them check the fit first. If there is a problem with your bobbins, you'll have to take care of that first.
I originally bought r.d.'s first before I had heard of the Bank's kit. The Bank's kit seemed to be easier to set up so I used them. Since I only have experience with the Bank's kit, I can't say which is better/easier. The Bank's kit has the advantage that it allows you to take the door off and you'll only have to readjust the height of the door. I'm happy with the Bank's hinges.
