Best way to remove starter 318 newbie question 67 cuda

Forget "rebuilding" and this is coming from a guy who at one time "would have" and "did." Do yourself a huge favor, buy a rebuilt and ask for a 90's 5.2 or 5.9 Ram / Dakota. This is what's commonly known as a "mini starter" and they work way better and weigh about 1/2 as much

You don't have headers on your car? then easy. Unhook the battery ground cable. Most of these are 5/8" socket, you need either a box end for the top one, or a long extension and ratchet to reach "over the top" of the starter.
