Hard luck there Buckland. You can maybe try ringing around some (as many as you can find) suppliers of chemspec products (cleansmart, restormate etc) and see what they can do for you. As i said in another post, alot of suppliers wont list everything they stock or can get their hands on, on thier website.
If I am not mistaken, all of chemspec products including chems come straight from the US. There's no European plant, so which ever way you look at it your still going to be getting it from the US.
Does it have just one vac motor in there? Does it have to be the same exact part you repalce it with?
