OP: I have a set of Westin ones in black that the previous owner bought for my vehicle, 85 K5/CUCV, you're welcome to them if you pay shipping. May be crazy expensive to Canada even though I'm actually not far from you. They came with the truck and I don't intend to install them.
Not sure if mine have the mounts or other hardware with them.
FWIW...I have the same exact design/brand on my daily driver MDX and while I wouldn't say the step portion is ever slippery (even in snow or mud), it could use some extra grip, perhaps just hitting it with a palm sander and 60 grit might do the trick. Then again I rarely ever step on it, usually only to reach into the car to put groceries or packages in and get them out.
