It depends if you've got the standard 1 piece tailgate, 2 piece (where the glass also pops up) and if you have the pop up and the larger rear tailgate moulding..
Get the wrong ones and you could ping the boot open very rapidly or need extra muscles to help you..
They all retail between 15.67+vat - 17.93+vat.
If you want a correct number and price PM me with your chassis number and I can price them at cost for you and could post if you like..
