I have a spare long side 2.5 ton u joint style axle with tight u joints and the stub. Slightly rusty from being out in the weather a bit but nothing major. It has 16 splines as I recall. All splines good condition! Splines a bit dirty can probably be used as is or you could quickly clean up to like new with a little wire brush action. Dimensions are 12.5" tip of axle to center line of u joint for the stub end and 23" from tip of axle to center line of u-joint. Can send pics if wanted. Weighs probably 50 lbs shipped so $175 shipped to your door or best offer!!!
