Hopefully I dont get grief for this, Steve? there is a great resource for all of us IH owners here, its another forum called The Binder Bulletin, anything IH can be found there, but be forewarned,, use the search feature before asking newbie type questions there, as there are many ehem, purist/elitist/buttheads, that will kinda rip on ya, but dont let that put ya off, there are really a great bunch of people there. It is mostly geared towards the scout/IH lightline trucks, but theres something for everyone, and when it comes to engine parts, Lucky us, it all interchanges. So without further ado.
