warm up regulator

I am hoping someone could help me locate a new or rebuilt wur 0438140153 for my 86 preciated930. The wur that came with the car when I bought it is adjustable not sure where it's from.The problem i'm having is I have to adjust the warm pressure down to 2.8 bar to get the afr readings in the 14's so now my cold pressure is 2.2 bar and the warm is 2.8. I have read on here that a sign the wur is failing is when your cold and warm numbers have to be close to run. Any help or advice would be appreciated. Thanks.
