Replacing the vent wing knob
by Karl von Salzen
You don't need rivets or to disassemble
anything. ALL you need is a 1/64" pin punch and a good knob/arm.
Look at the base of the chrome arm and you will see a roll pin
going thru it. Drive out the pin and the arm comes off. Find a bus
in a wrecking yard with a good knob/arm on it and drivr out the
roll pin. Install it on your window. Watch out for the 68's, they
do not use a roll pin and you cannot replace them. Here is a pic of
the two different versions:
The one on the left uses a roll pin and is
replaceable.
The one on the right is the 68 version,
but I have seen them infrequently used up to 71, is not repairable
easily.
I have a few extra knobs w/arms if you
can't find one.
