8 3/4 bbp axles on the cheap?

I think if you want to keep the tapered rollers you are forced to have C-body or van axles cut down, or spend the bucks for Moser axles. I asked a couple of dealers if the OEM type bearing could be put on a Yukon axle and was told NO. I asked why not and they couldn't tell me. They insisted that the Green bearings will be fine. I asked if they would put their money where their mouth is and GUARANTEE the Green bearings. They said NO.
