Agkits A Tractor parts company selling complete engine rebuild kits Iowa!!. I orded parts for a 152 perkins engine in a massey ferguson. I order these parts with engine model and ser. number tractor model and ser. numbers. these people sent parts alright. I had to take them to a machine shop and get them machined to fit. In there kit was gaskets most of these did not fit.To get the engine back running i had to go to parts store and match up gaskets these people are a joke . I have never had such a hard time getting what i needed to rebuild an engine. I have reciepts for machine shop bill and gaskets. There are alot of companys that sell the parts use another are be sorry.
