Chuck,
There was a large whale tail/deck lid for sale a couple of years ago, I think it was either in Michigan or in Ontario Canada, I don;t know what you would use as a picture, but you might try putting a "wanted" ad on the Samba.
Best regards,
Jim

I bought it along with its deck lid. I understand the spoiler was an option on cars sold in Canada.

Al did you get the yellow one that was listed a few years ago? Did you install it or have pictures, I tried to get that when it was available but I did not get any response.
