MGB Convertible Top Frame Mounting Screws
All MGBs from 1969 onwards use these screws. Each side of the top frame is attached to the body with three of these screws. They are ¼” screws, about 1 ¾” long.
They have a Philips, countersink head with fine thread. It is difficult, if not impossible, to get these screws at your local hardware store.
They become loose in their holes eventually. They vibrate and the threads get stripped or worn down. Left long enough, it ruins the threaded holes in the body behind the doors. This is extremely difficult to repair properly.
Don’t let this happen to you!!!
