Induction (intake) manifold used on 1973 Volvo 1800ES

I am searching for the engineering drawing  for induction (intake) manifold used on 1973 Volvo 1800ES. I don't know who manufactured it, but the stamping is varied -- JM or KM plus the part number -- 1-460270.

Hi,

this seems to be wrong question for this forum. We concern about Jetronic and Ignition systems.

Isn't that induction manifold part of the Djet system?

Yes, Jim -
the intake manifold has been engineered to adapt the DJet-system.
This is a very specific part, engineered not by Bosch, but by Volvo and you will not find any drawing besides schematic ones here or elsewere.
I think v1800.org could be a source for a schematic drawing.
