71 340 PDB master cylinder spacer question

[ricomondo]

I’m not too familiar with these spacers for the PDB master cylinder?
Which side goes to the rear of the master? I’m assuming the round side and the flat side goes to the booster?

Also I have three gaskets? Which gasket is correct for this application and does it go between the rear of the master and the front of the spacer.
Looked in my FSM and it wasn’t much help?

Thank you!!

IIRC, the plastic goes against the master cylinder and the metal side goes against the booster. Those gaskets are for the firewall under the booster re-enforcement bracket.

@cudamark - thank you!

Also so there is no gasket from the master to the spacer? I was thinking the top center foam one pictured?

No, I don't remember ever seeing a gasket there.

Ok, we have the first part figured out. Have the round portion in pic4 up aginst the booster and the spacer mounted. Now does a foam gasket (pic 2 top gasket) go in-between the back of the master cylinder and the front of the spacer? Or no gasket between the two?
