This is Halfords we're talking about, they may charge me for the replacements so I'd need to add the value into the voucher I'm about to order. If they don't charge me then I can just use the excess for any other bits so it's not a problem. But I really have no idea what I'm looking at which is why I asked for specifics (ie links so I can see the price). Not trying to be pushy but my mouse is hovering over the order button!
