shower drain repair


I have a Mustee 48.105 model shower pan, about 11 years old. It leaked and we found that the flange of the drain was cracked. The plumber removed the male part of the drain but we cannot find a replacement part. Mustee does not make them any more. The part we need has a flange that fits over the hole in the shower pan, extending over the shower pan about 1/2 inch, and extends about 1 inch below it. The portion extending below has 11 male threads, spaced at 11 thread per inch. This male portion is about 3 inches in outer diameter. The female part that it came with is still connected to the trap. All replacement parts we have been able to find have 9 threads per inch and will not fit properly. Does anyone know where I could get a part like this? Can anyone recommend a plumbing supply company that stocks unusual or out of date parts? Is there any other approach we could use to replace the drain of the shower pan that will not involve removing the shower pan or cutting into the ceiling below?

Looked like this one? http://www.oatey.com/apps/catalog/showskus.asp?ctg &subctg=4&prodgrpid7
OK. I will take your word for it that the ceiling simply *must* not be disturbed. If it is that vital to save the ceiling, and the part is NLA, then you might be forced to have the male threaded part made-to-order. Or built up out of 2 or 3 parts.
Sounds like a time-consuming effort no matter what. Jim

Yes, the part looks like that except for there being 11 threads along the inch. I already called Oatey and they say theirs have 9 threads per inch.

Do you know a company that can do this? The ceiling below is our dining room and it has a swirly textured pattern on it that is repeated everywhere through the house. We have previously been unable to get this pattern properly matched (in a repair done to our basement). If we cut the ceiling, I think we would need to rip down the entire dining room ceiling (or else we'd end up paying a lot of money for a cosmetically unsatisfactory repair). Even so, it could not be repaired to match the adjacent rooms, we would have a different pattern in that one room from the entire rest of the house. The water damage to it does not look that bad and I think it can simply be painted over. I hate to get into replacing the whole ceiling for lack of a $30 part.

Ah. That makes sense then about the texture. When you repaint, use Kilz to keep the stain from bleeding thru.
My approach to this would be to buy the new Oatey part and carry it around, looking for a part or parts which could be modified or machined for the 11 thread spec.
Or take to a small machine shop and have one hogged out of plastic bar stock. Or even out of brass!
As I said, could be time-consuming.
