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?

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.
