Hi.
This is one way to remove plastic clips.
The first clip I tried to remove. Knocked the pin thru, never found it again.
Next one, knock the pin part way out and broke the clip.
Looked thru the tool box and found a metal dart. The type that you throw
at a dart board.
Place the dart over the centre of the pin and with a hammer, begin tapping
the dart,(gently) the point of the dart will go into the plastic and then it will
start to move the pin, so keep tapping until the pin has passed all the way thru.
Now pin will be still attach to the dart, gently lever up clip, while still holding
dart, once clip is free of chassis, lift up dart, clip and pin will come will it.
Remove pin from from dart end, slide off clip and put in jar.
I have since sharpen the point of the dart a little bit, just in case of a loose pin.
So far so good.
