A couple more things about this old style lock out that can help Stefan.
This part is not made up to the same standard as a Hurst shifter box everyone
is familiar with. The great engineering and design that can be manhandled and collect years of
road grime and still work is not built into this part. It takes very little for them to malfunction and lock up.
The spring that creates the detent or holds it in selected position
is barely adequate. It will move out of position easily and can stop the function
of the part. Always check position of spring before sandwiching between mounting pad
and shifter box. The foil decal (#4 on instruction sheet) is important. This keeps dirt and road
grime out of mechanism. Aluminum furnace tape can be substituted on a used part.
If the spring breaks a new one can be made by carefully bending a Bobbie pin into shape as a replacement. Not easy but can be done.
Hurst did not make this style lock out very many years and moved on to better designs.
Unfortunately it was what they had to offer when our 68s were new. They do work if a close eye
is given during installation.
