60 Lark - 
I have installed new windlace in my 1960 Lark 4 door and retained the
old headliner. Heres how. Cut away the old windlace, or pull it out. 
Carefully, with a pair of needle nose pliers,try to grab a piece of
the headliner through the area that the windlace used to be and force
it upwards,gently, no more than a eighth inch, maybee a little more, 
so that it becomes disconnected from the serrated edges of the
retainer. You should be able to  pull a small section of the headliner
down. Once you have a piece down that you can grab between your index
finger and thumb, use a rubber spatula to push up the headliner from
front to back. Once you release part of the headliner from the
sawtooth looking retainer, you will possibly see what you are up
against. Try an area about 6 inches first an try to see what your
objective is. Basically the headliner is tucked up in there and just
so happens to grab on to the saw like teeth.  Once the headliner is
released from front to back, just the sides it should be very evident
how to install the new windlace.  I sorry if this sounds confusing but
it is the best that I can tell you. It can be done.
