Rad-era Euro freaks, help me find this seal

This is a tail light seal (between housing and body) for an '86 Saab 900; OEM was Hella, and the seal looks generic to me:

I assume Hella spec'd it and used it on other cars. Recognize it? And know where I can buy some? Here's some rough dimensions and a clearer, non-squished cross-section:

These guys have been recommended to me but I've have not bought from them yet.

Metro molded parts is the other supplier. 

I have excellent luck emailing Metro a cross section and them finding something. I'd send them your drawing and see what they say

Let us know what you find out, Tyler's car will need them at some point.

Thanks. I'll email the vendors above -- I saw their sites earlier and was kinda overwhelmed by the catalogs.
