Hi René, the striker plates are handed MBC 1700 right hand and MBC 1720 left hand, so I'm assuming you would need the latter for drivers side. The mushroom shaped part you describe as loose appears to be riveted to the main plate, particularly as there is a flat side to mushroom head which has to be at top. It's possible if you removed the whole assembly you could re-rivet or even have it welded into place from the rear.

Simplest would be to buy another if available in reasonable time scale of course. Closer picture here, part 23
