Another great site for Lambo replica enthusiasts is lamboclone.com. A lot of great folks on both those sites and should be able to help with Lambo parts.
Sometimes is its not much more and better quality just to buy the OEM stuff. Euro Spares is out of UK and has OEM and reproduction stuff. Another good one is bull stuff for Lambo stuff out of Ohio. If you do head over to Mad mechanics maybe ask K9cop he can probably steer you in the right direction he mostly does Countach Parts.
Neils88 is right they are cheap I was able to buy OEM turn signals from them for $250 for pair compared to $580 and up every where else. I have bought replica badges before you will be disappointed with quality. Honestly only good replica parts came out of naerc in Canada but no longer in business all the others were very bad quality. What other parts are you looking for? Check out Lamborghinireplica.com there is a seller selling replica steering shroud and engine cover if you are looking for those. Hvac replica is very hard to find as rice burner no longer makes them. Ronptcrusier on eBay sell a whole replica decal set and other parts item number 152450580998

I have also used Lambostuff for the nose emblem (pic & link below). The oem emblem costs about $500, and the replica (below) cost me $49. I really like it and I doubt anyone will know that it's a replica.
