<VV> Memory test -- parking brake alarm switch

[Kirby Smith]

As a further note, it is strange that the image of the brake alarm 
mounting instructions that Joe West pointed to was generated in 1961, 
but the P & A lists the part for the 1967, even though the mounting 
bracket shown in the instructions looks identical to the one supplied 
with the switch, and the bracket has no utility when the switch is used 
in the door jamb.

Anyway, thanks BBRT for your contribution
