Mate if you are still in need of one let me know I can get one USED for you for not much and can have it posted ahead of the other stuff you have here awaiting the wheels.
Posting will be aprox. USD$37.00/GBP20,00 for 5-8 days Air service and aprox. USD$50.00/GBP27,00 for the Power Steering Pump.
NEW pumps are aprox USD$170.00/GBP90,00 have not priced then latelly and they will take a few days to get to me then out to you.
OR you can also get the rebuild KIT for the pump for aprox. USD$25.00/GBP15,00
Let me know if you fail to locate one locally or if you would like to get a new one.
