Hi again I am going to rephrase a question from a while back that I didn't get a response on. Does any one know if a model 771 Erie pump has or needs frame rails? mine didn't come with any,--- ,if it does where do they go or what do they look like? Also does any body have a diagram or picture of the door latches and hinges for the same pump? mine were torched off and I have some pretty rough pieces, thanks for any help. Mike
