I am installing a left sliding window in my J3. Since it is a Supercub style window, and the guys at the J3 site will yell at me for changing it from the original I thought I would ask here.
Can anyone post some photos on how this is supposed to be welded in the fuselage? The problem I am having is with the upper slider. I assume the reason is that a supercub has a tube for the upper channel to weld to and the J3 just has the channel. Should I be able to just fab it to work or is there a recommendation or a work around to use the PA-18 upper slide.
