Hi!
Ryan Abreu, I had the same problem with the ND filter Wheel, but in my case the filter that popped out damaged the “pre sensor” ( i don’t know if is this the name, but its the glass that comes under the ND filters wheel).
I found a page from sony that seems to be for replacement parts, but, as you, I didn’t find the part number, so, today I tried to contact them, explain the situation and see if they could help.
