cobra side pipes

Howdy! I'v noticed a few Cobra builders here, and it go me to wonderin'... Is anyone here puttin' one together in the SF bay area? The reason I ask is... I think the side pipes might fit my project, but I'd like to try and fit some up just to see how close they are before I go through all the riga-ma-roll of ordering 'em up and finding out that they won't work. I'd be happy to pay anyone for their efforts. BTW the engine in question is a 351/400M.

Didn't know there was such a thing...
Just a shot in the dark... Ya never know. Thanks for the link.
