Ok guys, so I've sourced a replacement axle for my 510 build. However, the new axle had the bearing spacer removed (#6 in the photo), and its the only part holding me up from slapping everything back together. I was wondering if anyone knew were to get one, or had a part number that would help me track one down? Also, is there any way to remove the one from my bad axle  and put it on the new axle without damaging it? Thanks in advance!
