Door panel installation

[Dave K.]

I had to remove the drivers side Al Knoch reproduction door panel on my 66 convertible to repair a broken vent window T-handle shaft. The door crank handles and lock knob came off with ease and the panel came off after a little upward bumping. The T-handle repair went well but now I'm having a difficult time re-installing the door panel. I can recall some 6 years ago when the panels were first installed that we had to beat on the panels with a rubber hammer to get the metal backing support to seat over the fiberglass. I'm reluctant to beat on these panels any more than necessary.

All and any tips are welcome.

Regards,
Dave K.
