So I'm finally getting around to working on my whizzer and I'm having a mechanical meltdown on what thought would be the simplest of tasks. I'm just trying to put those special nuts on the rear axle to hold the drop stand and It's not working. The nuts thread beautifully on the front schwinn drum brake axle that I just got from Memory lane and the original rear axle hex nuts thread on the front axle like they are a perfect fit, but when I try to put the nuts from the from the front axle on the rear its a no go. The rear hub is a bendix and appears to be 3/8 by 24 threads per inch. I'm thinking that the schwinn axle is like 1/64 smaller in diameter? Just enough so that it won't work, Please help if you know the answer.
