Hi guys I just wanted to know if someone could shed some light onto a problem that I have, or if I am not mounting this up correctly.

first picture you can see the webber carby sitting on the carby manifold.
Second picture is a pic of the bottom of the carby manifold where is bolts up onto the exhaust header.
third picture is a pic of the bottom of the carby manifold and where it bolts up onto the exhaust header.
The fourth pic is a piture of my extractors which is replacing the exhaust headers but the extractors do not have anywhere for the carby manifold to bolt onto, so I am not too sure what needs to happen with that.
Any help would be greatly appreciated.
