Count me in on the buildoff. This frame is the first rat bike I've ever owned, it's gone through many different build phases so why not a klunker also? I have a question: What are the rules about using early 90's BMX/MTB parts? Are there any or is it just open to any parts you can find? Late 50's Firestone 500 26" frame and monark springer steer tube, plan on creating a crude looking front suspension. 90's Free Spirit 24" I plan to use the wheels/back brake off of this.
