Grantura 2 bits

Hi - can anyone help to identify the type of manifold used for early B series engined cars? Similarly - how/where is the exhaust system routed to achieve best ground clearnace?
Also, I am trying to identify the dashboard switches - they appear to be Morris Minor pull switches on the photographs that I have seen. Any info much appreciated!
Cheers,
Mark K.
