1997 honda foreman 400 front pinion

hello, trying to remove the pinion nut off a 1997 honda foreman 400 front differential. Ive tried everything by that I mean rigging tools and also tried 1 1/2 piece and it will not fit which everyone says it should. Im finnaly buckling down and buying the actual tool needed to take this out. I went and measured the nut and it shows 1 15/16 inches which converts to 50mm. The only pinion nut removers im finding are 60mm and 64mm and people have been saying the 60mm will fit but also people say the 64 will fit which does not make since because my caliper is showing 50mm. If someone can tell me where I can find a 50mm pinion nut remover it will be well appreciated!
