I would check with Bud Klemp, parts manager at Checkered Flag VW. He has been supplying parts at great prices on the Vortex for quite some time and really knows his stuff.
As an example, I recently purchased the VW fog light kit for my Routan from Bud. List price is around $290 or so. The best price I could find was around $230... that is until I contacted Bud. His price was around $135 shipped, new in the box. He is very helpful and friendly. The parts were shipped quickly. (And, no, I do not have any affiliation with this dealership.)
This is the contact information he lists in his posts:
