Seeking GT-6 Weber intake

[Russ Moore <rem9@cornell.edu>]

I am looking for an intake manifold that allows the use of triple Webers on 
a Mark 3 GT-6. Manifolds from the earlier Mk 1 will not work as the port 
configuration is different. This manifold is distinctive from the TR-6 
(2500cc) in that there are "gooseneck drops" to lower the carbs and allow 
for bonnet clearance.
