Shure SM91 Internal Foam

[egroys]

I decided to clean out an old Shure SM91 that I recently acquired and when I opened it, the foam was half torn, and half dust. I removed it entirely.
Google shows that it's "Shure 36B686" and the one source, Full Compass, shows that it's out of stock.

I'm assuming that it's probably necessary to have the foam for inside kick drum duties?

If so, I'm curious if any one can suggest how I can procure or DIY something correctly for this?

Thank you all in advance!!

Is that the same part as for the Beta 91? If it's not, they can't physically be terribly different, so maybe look up the Beta spare foam?

Good call! But I am seeing nothing for the Beta 91, unfortunately...
