Tool...
As I recall, there is a tool that allows the removal and install of the headliners for the 326. It has been a few years, but I had a picture of one e-mailed from Hunter, but was lucky enough to be able to borrow one from my dealer. It was a piece of 3/8" aluminum plate cut like a "C" if I remember right.You might try your dealer and see if they have one, or Hunter to see what they can do for you.
