Proper Ducktail Mounting bolt size??
 

I am installing an aftermarket duck tail on my SC and am wondering what size bolt it takes. The ones from my original deck lid do not seem to work, but I have some 10mm that seem to fit. My concern is thread pitch any ideas?? thanks

Hey Dean, where'd you get your duck? I'm thinking about installing one on my '79. Post pics will ya?

No problem, I actually posted a wtb in the parts section and got several replies. I however ended up buying my old tail from guy I sold my 66 911 to. I also bought my 86 Carerra seats from him too. Funny I sell the car only to buy back some of my own parts. Not cheap either -- Well actually fairly priced.
