Which 'bulbs' are you tryin to change?.. The bulbs that illuminate the speedo are on the rear of the speedo box, you don't need to dismantle the box to get to these they just twist lock into position, if its the led's on the front of the speedo box which are your warning lights indicators oil ect, then replacing them is a bit of a mare so you probably would be better gettin one of the olde eBay, just make sure part number is right first!!
