If you are seriously looking to add a bodykit to your Hijet van then your best bet is to look at places such as Japan. And it wont be cheap.

It all depends on what you want to do to your van. Things like alloy wheels, then you should be able to find something on ebay for it.

I just did a google search and seeing whats been done to hijet vans then yes it can be done, but boy i dont think your van would be useable afterwards and forget about getting over speed bumps
