Thought I should jump in and let you know your question isn't being ignored, but rather it is just that there are not a lot of parts sources for cars outside the mainstream. Not that your car is odd, but it is just not as popular as lets say a 48 Ford, so the parts manufacturers are not as apt to want to make parts for them. They have to devote their resources to cars where they have a better shot at selling a LOT of parts rather than a limited number.

If no one here is able to help, you might consider one of the make or model speciific forums. I don't know what forums there might be for your car, but Google is your friend. Good luck.
