I'm killing myself over this basically because I can't waste money on buying wrong parts and it's something new to me that I've never done before....I have a wanted ad for a 24" fork with 5 inch tube, and I can't find a replacement to specs with that. I can spend $40 on ebay and buy a fork with an extra long tube and cut it using a pipe cutter (the threads come down far enough to work), but my question is can I get away with buying a fork with a 5 1/2 inch tube or is that half inch going to screw me up? I also see headset spacers, any way I can use them with another fork I have with a steer tube over 7 inches? I've never mated a different fork to a bike before, so I'm scratching my head and not wanting to blow money... thanks!
