NOTE: Factory Service Manual provides a “slightly” different procedure. NO “SHIMS” were needed, new starter fit perfectly. Having never changed out a starter on a 84 Vette before, I TOOK MY TIME , about 1/12 hours, to remove the old one and install the new one. Now I could do it again no problem. OEM AC Delco replacement starter from Eckler’s Corvette. Before attempting this job, I would suggest referring to the GM Factory Service Manual. I did not remove the flywheel and I did not have a problem.
