We have been trying to retro-fit cassette blinds to our 1983 Crown van. Someone put me on to a breaker at Talywayn, between Abergavenney and Pontypool and we got blinds for the side windows. However, we have single, one piece front and back windows and they're not so easy. Does anyone know of any other good yards, particularly in the West Midlands/Welsh Marches/Mid Wales areas?
