There are many wood components from header bow, rear bow, base line and 1/4 wood that may need replacement. Also, the rear window frame distorts and doesn't allow the rear window to seat in position( I always purchase a replacement frame with wood tack band and new rubber ) Check out M&T Manufacturing, they are very helpful. I usually figure labor for top,pads,cables and headliner at 20 hours. Wood replacement labor additional.

Thank for your input, very helpful!!

We charge 12 hours labor to install the headliner, pad, convertible top & rear window. Always needs a new window frame and seal.
