This is it Ive seen box's go coming off a roundabout at 50 and then puled a little in third and gone but if dean hasnt got the cash to do a bigger box then thats it ! I made sacrifices to get my box in the engine bay which is like a dump suffered but hopefully I wont be changing a box anytime soon , but if i was in his position I would just get this on fixed and get saving as it will go again and again so by the time you work out cost to do so the 2.5k will be a cheaper option
