Hi Diesal fans, I am running a 6.9 FORD,It wasen't bad to fit, But I did have to keep it high in the engine room do to the starter being on the front shaft side.(I broke one starter off and bent my shaft on another ocaision,had to make a new adapter that goes between the engine an tranny which holds the starter then I added some over load bumpers to limit the front end from going too far up.)
