Default Where to get 740/940 floor/defrost vacuum bellow?

I have a 90 740 turbo, and the floor vents are not working. On the floor setting, most air goes to the defrost. Used a mityvac and found that the floor-side of the bellow will not hold any vacuum. So, I need a new bellow. This is the one with the yellow and blue vacuum lines going to it.

From what I can see in the parts catalogs, the part numbers are 3522945 and/or 9463042. Not sure if one supersedes the other, or what. Either way, everywhere I look, both are NLA. Is there a new part number, or some different replacement part, or can anyone recommend a place to try to purchase a new one?

This is the car list it fits:

780 1987-1991
940 1991-1995
960 1992-1997
S90 1997-1998
V90 1997-1998

So I find it hard to believe they'd just stop making it, with no other replacement options...
90 Volvo 740 turbo wagon
85 BMW 325e, 4.4 v8 swap
89 BMW 535i

Someone else more experienced than me will hopefully chime in, but I think that's the one that's been NLA from the dealer for awhile now. I know the one on my car doesn't really work either.

My best suggestion is to grab one off a later 960 or S/V90.

Edit: volvo944ti is parting out an '98 S90 in for sale, you could ask him.

Current Cars:
1987 Volvo 740 Sedan ~180k - awaiting complete disassembly and scrapping

1989 Volvo 740 Turbo Intercooler Wagon ~155k - hardware store mbc + 4.10 final drive + horrible fuel economy + dead blower motor = favorite daily

1995 Volvo 940 Sedan ~183k - undecided fate (too nice to scrap, too boring to keep, too archaic to sell)

Pretty sure my mechanic replaced mine with a new one, but I'm not sure where he got them...

We really need to design make a newer better version cause these bellows royally suck... My recirc bellow is out and there is no good way to replace it short of removing the dashboard...
