Topic: Midland VS Bendix: Spacer between booster & Master Cylinder

[Angela]

Is the oval-shaped Aluminum & plastic spacer supposed to be used between the master cylinder and both Bendix and Midland boosters? Or, is this vent/spacer only used on Midland-equipped cars?  The spacer/vents I have appear to fit both boosters.
If the answer is specific to production year, please let me know. I am specifically asking about model year 1970.
Thanks!

Aluminum and plastic spacer (with the foam filter) was used solely on the Midland boosters.
West Coast Classic has the best YouTube video known to me, for identifying the boosters and correct parts. I don't think a Midland booster was used at the factory on the 1970's but I'm sure some have been swapped onto them throughout the last 52 years.
