need a cheap wabco air compresser for d2

Im going to fix my compresser as the bushes are worn im taking pics to do a thread .but wondered if any one got a old one cheap that would do for now in the Holbeach area or further afield.

My 2001 disco has been converted to springs but still has compressor underneath, is it a huge job to get it off? I'm dorset though

No It took me about 10 mins as I could not get the main box off which is two bolts and two air pipes and two plugs. I undid the pump itself three bolts if I remember. How much are you asking for it? Mine was on air originally and someone had changed it to springs but I want it back to air and when I checked my compressors it was rusted up.
