Might be an idea combing through our shop - we have the genuine Dayco belts cheaper than the eBay link, and our work supports the Forum too.
Hopefully we'll also have the Rear Upper Arms in at a price that's lower than £99.00 on eBay, we're negotiating a bulk discount at the moment.
Edit: Better add our £29.99 Thermostat Kit if we're talking bargains!
