Re: 1975 interational, v345
You dont have to look for the specific year - 1975.. Just in the range, most all parts are the same,, except for things like carbs.. And you need to look for truck/pickup parts as the parts house wont have school bus parts... and most of the employees dont know to look for a general engine type instead of something specific on the computer.. Napa would either have the most parts or be able to order them.
like i mentioned before.. get a shop manual with that engine and in the 1970 range... like chilton or motor manual. I also had a 1966 1 ton pickup that had the same engine in it... come to think of it.. i had to grind the valves in that one also...
