I have a pair of Mount Logan Offroad 35 spline drive flanges that have been sitting in my room for MONTHS. They have never been installed in an axle. There is a slight bit of surface rust that you can see in the second picture, just from sitting in my closet for months. Wouldn't think things would rust there, but sure enough they do. Couple swipes with some emery cloth and shove them in their greasy hole and never worry about it. I think I paid like $180 for them, I am asking $110 + the ride. You can contact me by PMing me on the board or email to Alan@mandic4x4.com. Simply replying here isn't a very reliable method for reaching me.
