Try midland group for some of your forklift parts. They are local to us, so we use their trade counter virtually every day. I know they send a lot of parts all over the UK as i have seen the carriers in when picking up our stuff. They have increased the product range significantly ovetr the last 18 months and are one of the cheapest around imho. (midland-group co uk)
