SO! ended up finding an old blueprint carrying tube from the 40's maybe? it's just thin steel, with a cap that comes off. so i chopped it down, cut it down the center, and with a little JB weld, got myself a nicely sized compartment. turns out PVC and other piping were in between sized just enough for me to make it NOT work. gotta say i love the rust look of it, but i might hit it with primer brown to clean it up. getting the new battery in tomorrow so i can finish up the wiring! OH and the seat came from choppersus.com!
