how hard is this to do

i crunched mine yesterday so would like to replace it with a 6n2 one if its not too difficult

you cant just put the bumper on you need to do the whole front end

bonnet, lights, bumper, wings and slam panel

And part of the metal plier behind the wing needs cutting and a few other bits

ohh right i thought i had seen people who had just used a 6n2 bumper in replacement of the bumper and grill surround

Sure your not thinking of a 16v bumper?
