I bought one of the $14.39 White Brothers Frame skids from eBay for my Warrior.

Quality and Fitment are Great!
I'll try...
There's a bunch of White Brothers, Warrior Frame Skids on ebay. New, for only $15 each.
Seem's like a great deal if you need a skid.
I ordered one.
I'll post a Product Reveiw when it get's here.
