When you have the inner trim panel off, you can see 2 of the screws that attach the exterior moulding(separates glass from painted area) on the outermost edge of the t-top. The other two screws are not visible at this point. There are two options at this point. You can go the time saving method of drilling the two bumps on the inner plastic frame to expose the last 2 screws. Or you can go the non-butcher method of further dissassembly (outer painted shell has to be removed from inner plastic frame)and take the remaining pieces apart. Sorry no pictures.
