Well thanks my mate that was very kind of you to offer. Fortunately I just had a phone call and the company who owns the wagon is willing to bung me the price of the parts needed, a few quid for my time in fitting them, and a little extra for being so nice about it. I found a set from 'Bikers stores' and as I am not paying for them I suddenly don't care about the cost. Happy days. These bikes are tough as old boots.
