Hello, long time lurker, limited poster. I actually vintage race a Z but was hoping you guys could help me out. I searched Courtesy Nissan's website and it looks like the L24/L26 square port header gasket, p/n 99996-e1044, is NLA. I'm bummed out, that was a really nice gasket, much better than the paper ones out there.

Does anyone know of a comparable one available or a place which may still stock the Nissan Motorsports gasket?
