8.8 swap

I cut 3 and I have about 1/8" of shiny axle on the end, before the center pin is installed. that tells me I cut it a little short, but since its a C clip, the bearings are about 1 inch wide and there seems to be a pretty wide bearing surface on the axle itself, exact is not necessary. I cut mine with a sawzall and then trued up the tube so I probably lost a few mm's. I feel I was close enough, but 2.875 would probably be closer to spec. You guys realize these weigh 170 lbs? How much does a practically sheetmetal 8 75 weigh?
