67 Chevelle Malibu (Convertible)
I have a 1967 with a 350, I have a AC Delco mini starter installed and the starter is dragging/grinding. This is the 3ed starter in 1 year, it works great for awhile then one day without warning it starts dragging. I go exchange for a new one, install works great, 4 months or so it starts grinding again, get a new one and it works fine….What is going on???
