nice, I just rebuilt and upgraded my 30 spline track lock to a 35 spline unit. Was a HUGE PITA to get back together. But I did. Then I realized last night, I forgot the damn thrush washers on the spyder gears, so I get to take it all back a part.Actually, yes. I have one I rebuilt for my Ford truck I need to get a broken roll pin extracted from so I can install it.
