Did the moonroof mod myself and it was bloody hard work doing it on my own. Its simply straight foward, swapping the old for the new and i must say the new suites the raddo just fine. After fitting and bolting the roof in you might need to adjust the four screws (two on each sides) which the glass is bolted on for the perfect fit, simply by loosening the screws and pushing the glass up abit until its leveled with the roof and then fasten them back. Oh, don't forget to connect the drain pipes.
