Intake for a 4 BBl Carter AFB and an Exhaust Manifold for RX7. These have been obtained from Cali.
12A Turbo Intake Manifold for 4 bbl carb and Exhaust header are For Sale.
The 13B is 3/8" longer than the 12A we are told. Front cover from 12A must be used as it incorporates Front Motor Mount.

Can anyone tell me what the small round electrical switch at the end of the 5 speed TailShaft is for? Neutral Switch or Backup lights and where can we get one?
Please call 905 689 4363 ask for Harry.
We are in Hamilton ON Canada.

Thanks Jeff:
We are changing out a customers engine and need the manifolds for a 13B 6 Port Engine in a RX7 1981.

None available from Dealers.

 

The request is somewhat confusing but I'm gonna take a stab in the dark here...
