Getting to work on my Huffy cruiser and have found a few problems... 1. Got the battery tray that partsguy suggested and tried to hook it up only to find out that 1 bulb was missing and I don't think the other is good. It's marked 2.5 volts. Where can I get replacements? 2. I pulled the crank apart and the inner race is not threaded same with the crank ( does not appear to have been threaded). Is this unusual? 3. The rear fender stays are bent bad, what other bikes use the same ones?
