Hi,
Is yours a short wheel base? I looked for my dciv which is long wheel base and they didn't cater for it but they do for the short.
I have the rear spoilers from trade van accessories, they do a full kit. I think vanstyle also offer one.
eBay has many but I have no idea as to their quality.
You could also try dedicated tuning/styling houses who do the conversion for you. I rang swell vans in Poole, very impressive conversion and really know their stuff but not cheap.
Swiss van is another good looking conversion kit.
There are a few options out there.
Enjoy your new van.
