I have a 65 Stang with 289 and C4 trans. Had to replace the starter(original) with a new one. After I removed the bolts and was pulling it out several thin washer fell out. I now know they are spacer shimes. I have been trying to put them on the new starter in different combinations, one on each bolt or two on one bolt. How do I determine what I need or how many. I know if the spacing is not correct I can damage the flywheel and the new starter........help.
I had to change mine also. I did not put back any shims. And no problems at all.
if you have the correct starter then there is no need for shims. parts books are notorious for mixing up the auto & manual starter p/n's.
