sorry i dont have them mate but this guy should have one http://www.jdmotorsport.com/ If its not listed on that site try his ebay shop http://stores.ebay.co.uk/JD-Motorsport

I know the servo is the same as the other escorts as i used one from the 1300 escort as the rs one was rusted to hell, not sure what other cars use the master cylinder tho as it has pipes for the abs on it. The xr3i one mite be the same?
