^^^ you mean your mats have the holes with the grommets in them? (sorry, a little confused in how you used the word grommets)
i have the grommets in the mats, but in my current E30 i dont have the mount points on the floor board. can you just get these from the dealer?
i asked this question prior to getting my second E30. my first E30 had electric roof, the current has a crank, and i dont mind the crank (i can actually open it faster with the crank then with the button), but i find myself opening the roof less than i did with the last 30. . .
