Greetings,
I've not used this service for VX parts but it was a life saver for some custom parts I needed on other cars.
It is www.eMachineshop.com --you download their free CAD program, make your design, upload it for a quote, and then they machine it and send it to you.
I've had things made in nylon, stainless steel, and aluminum. Simple things in cheap metals are actually not too pricey.
Of course, the trade off, is that you have to design it, but the software only takes a couple days to become comfortable with (although I'm no expert.)
Regards,
Mark
