Hi Vanagonians!

I need some help. My '84 Westfalia has been in the shop for a few months now, getting the AC system fixed among other items. It has the in dash Behr type air conditioner. It's almost completely fixed. The very last thing my mechanic needs to complete the repairs to the AC is a replacement expansion valve. He cannot find one anywhere. The current one says on the outside:

Made in canada
D84

I uploaded a photo of the valve to twitter: https://twitter.com/alexdecordoba/status/526882271819620353

Where can I find such a valve? Are there other compatible valves that would work for my application?

Many thanks!

Alex de Cordoba
