I used a small pick to poke the hole; it's just fabric there so the pointed rod for the visor bracket went through no problem after. However, they just flop on the rod, aren't tight enough to hold any position. A careful attempt at crimping in the area the factory ones were, made no real difference. They're difficult to push over the rod, and you'd think they would stay in position, but they don't. I'm really unimpressed and pissed off about it, but maybe I'm just missing some trick to make them work.
Good to know the LMC ones are made by Acme (same as I just bought from Rock), which I assumed was likely, since there can't be too many companies making the same items.
