jopes, i do the same thing and i am far from a newbie. i dont wheel as much as i like to, ive been building this thing for a while. besides, the squeaky wheel gets the grease. dude, i think the earlier axles even had thicker tubes. you should be good to go, but get a tape and ... oh heck, i forgot. you dont have one to compare to. i have one on my porch. i can measure a few things to give you some reference points.
I would show you off roadin pics but i dont have a camera. Why you got to be bustin my balls?? I am just asking legitament questions. If i had the information that a person was asking for i would give it to them. I just want to get as much information as possible. Someones got to start somewhere RIGHT!!!!!!!!!!!!!!!!!
