Renae,
Let me know what happens. Also, if you can record it when trying to start, do so and upload it for me to hear.
As far as shims, if there weren't any when you removed the old starter, it really shouldn't require them, but anything is possible.
If you look below, I provided the directions for the removal and replacement of the starter motor. I hope it helps.
Take care,
Joe
