I need to know if the diameter on 86-87 Big Red front axle bolt is the same as a 85-86 atc 250R, the smaller part where it goes thru the bearings on the hub, but also would be nice to know diameter of the outside part that is larger also, to top that of with the total length even better, so if any one has one laying around they can measure be greatly appriciated, I need it for my WR450 trike conversion, stock bolt needs to be a little longer. thanx for the help
