Hi. I purchased a rear sun blind for my 2003 X-Type. The kit came with the fittings that go into the headliner so that when the sun blind is retracted/closed, you can place the tabs into the fittings. The fittings came with screws, but it looks as though the fittings are actually "punched" into the headliner, then perhaps screwed into place. Does anyone have any knowledge of how I can install the fittings? Any assistance is appreciated! Thanks. Bill in Ohio.
