The plastic carrier that links the metal windscreen arm to the blade snapped on my Fourtrak & I'm having real trouble finding a replacement, Unipart, Express Factors etc. all stock the blade but not the carrier, I've looked on Milner's but can't find it there either. Anyone got any smart ideas/sources? I'd rather get new because the plastic on mine had become very brittle so a secondhand one would probably suffer the same fate soon enough. Thanks.
