Nope, the bit you need is only found on pre abs cars. You don't have to fit one from a Sierra, I am sure other cars use them. If you look in my build diary -
www.deepfolly.co.uk you will see what one looks like. It is about 40mm diameter and maybe 60mm long, it is tubular in shape and has a 10mm fine thread fitting at each end. I can't remember where it was fitted in the donor car, my donor had ABS so I had to buy a valve off ebay. It cost me a tenner.
Hope that helps.
