Joe, deezee said I have to enlarge hole with a dremmel. OEM was close to 2.5 inches, 62 mm. Starter is close to 66 mm. I enlarged with hole saw and then a round file on a drill. Got it close. Then switched to a half round file. Put a light behind the starter to find places that needed filed. Worked all day on the hole. Got it perfect. Starter bolts were both centered in the holes. Starter works as it should. Engine started on first crank after setting for almost a year.
3 days is too long to make this work. I even drilled and tapped the 3 holes in flywheel to use a gear puller to remove flywheel, because starter bolts are hidden behind the flywheel and my worst fear is removing the flywheel without using a puller.
Never do this again. If starter doesn't fit, I won't do it.
