Well my '70 GT finally left me stranded. After getting it home I found that when I tried to start it, the starter would just "sound" like it was spinning. It was missing the bottom mounting bolt so I thought perhaps it had moved away from the fly wheel. After taking it out and wiring it up, I observed spindle was moving out as it should. Yet when reinstalled in the car, with all the bolts this time, I am still just getting the free spin. The teeth on both gears look good. Do I need a new starter?
