I did a little research and found the head tube on an Electra Cruiser is around 1/8” longer than most springer forks .
Also read that some folks didn’t care for the springer fork on a “ regular” cruiser bike . Read they can mess up the steering and handling of a bike .

​​​​​​I could always do like we did when we were growing up . Just take a hacksaw to a donor fork , cutting the arms off and hammer them onto the forks , flipped of course to give that chopper look . Just don’t do any wheelies , the fork ends might come off . 😱
