I can't remember who's scooter I saw them on. I want to say either Andrew Broussards, or on Dylan Kasson's.... I could be wrong on both. But I remember someone having them. Pretty sure it was Andrew though.
I should talk Razor into producing their old grindplates. They snapped right onto the bottom of a B model. I used to run them, but they stopped making them in 03 or 04. I think Razor made a small batch, I was only able to get my hands on like three of them. A few others on Razor had them also. They lasted awhile, and could grind the roughest unwaxed ledge you could possibly slide on. Plus they wrapped around the drop outs all the way to the tip basically, and reached to the tip of the front of the deck. Made decks last a lot longer, no where near as much stress on the drop outs, plus no grinding. Just a bitch to remove and replace because they used double sided tape to help bond it to the deck so that they wouldn't rip off after awhile.
