Some questions....

Mikel is the nose cone on the starter broken or the housing it bolts too?

If its the housing It might be weak and you could get road crap in there.
But should be ok for now. Where are the pcs?

It was the nose on the starter. The gear looks ok, it's just the case on the starter. The broken-off piece came out when I pulled the starter out.

Auto parts store should have the universal for the style rear.
Since yoou have to replace it just remove it and take it with you.
If your ordering it measure the od of the cap and the width end
to end of caps on universal and ask tech before ordering.

Ok, good. I guess I'll pull it out and take it with me over to AutoZone. The front one looks to be ok, it's just the rear one. That's the one that gets taken apart all the time, so I guess it just had enough and gave up. ;-)
