Thanks tonk i have had a look and there seems to be a number of options, in your opinion which is the best way of doing it, i would consider buying a kit if its not mega ££££ dont suppose you are able to offer such a kit (noticed that you have done a few) or point me to a few websites that offer kits? i need to retain the series axles here as i want to retain tax exempt status and as i understand it by keeping the chassis, axles and suspension from the series vehicle that retains 9 points (where 8 are needed) and if im reading it right even if i convert to parabolic springs these are classed as stock as they are still leaf yes? cheers!
