Hey, you have to scroll through all the pages of the link to see if they even have the model and part you are looking for. I actually have a DBR9 that is missing the spoiler but I am settling for a V12 Vantage wing because the DBR9 is an old discontinued model. I will have to modify since the spoiler uprights are in a different position. Anyway, you have to be a member of the web site (create an account) and then Private Message AUTOartSpares with the model number and part number you want. They will reply and tell you how much it is. Once you pay them then they will update you with the shipping information. I have yet to get an update and will most likely message them today.
Hope that helps.
