Need Help with Speaker Replacment

[sheltonpg]

I have a 2008 SANTE 230 and one of my stock Polk Audio Momo Momo 6.5's is blown. I can't find these speakers anywhere but I know there is a cover that goes on the speakers. My question is has anyone purchased the Polk Audio MM651's 6.5inch speakers and used the original covers on them? I am not sure if it fits but I don't want to buy a speaker if it doesn't match and I defiantly d don't want to replace every speaker. I am attaching pictures of the speakers I am talking about.

Polk Audio 651um will not work because tweeter is built into grille. I just replaced 4 tower speakers in mine boat. Or you can buy a used set from buying section or ebay for spares.
