Really isn’t much to it. Not sure what welding ability is but make sure good amount of time, bevel both sides of the cut and I’d leave just a little space in between both to get good penetration to the sleeve, make sure to weld a couple plugs on both sides. You must’ve read enough somewhere to know roof will work and windshield will work with a little bit of treatment. Suspect you know to add length above front driver/passenger section.
Really pretty easy except center posts take a little bit. I personally leave the weld just a bit high around the cut while grinding to add strength in the weld, just make up for that with body filler. But that’s me.
