Regarding possible hard points for lifting at the rear of the aircraft - Kitfoxes have through tubes at the rear - get to a kitfox and it is pretty easy to see where they are - One short through tube at the front of the Vertical Stab has is designed to take the wing lock back bolt to secure the wings when they are folded - it's a pretty well reinforced point. Additionally, there are two longer through tubes at the bottom of the fuselage at the rear of the aircraft under the horizontal stabalizer - these are sometimes used for a tail dolly during building; or, a tail dolly when the wings are folded on a trigear (due to the lack of a tailwheel - my plane seems to lack a tailwheel to the chagrin of many of my peers) A trigear sits on it's butt with the wings folded too due to the CG shift with the wings folded)

OK - on the windscreen mods - where the rear spar bolts are located for the wing attach the windscreen (unless a builder has already made a modification) will be underneath the corner of the windscreen on the port & starboard corners - Again - find a kitfox and this will make make itself clear. On the front spar pins, there is normally a small aluminum cuff which goes over the area and over a portion of the windscreen at this position. Unlike the rear spar bolt location, during the build this corner must nave relief cuts around the pin under the cuff so the pins can be removed for wing folding - in all likelyhood, a person will need to provide a little more relief to accomodate the added hardware. You'll want to become familiar with cutting/working acrylic or polycarbonate (whichever the plane has for a windscreen) and become familiar with aircraft hardware as you will likely want a longer bolt for the rear spar location and replace the shear nut with a thicker standard aircraft castellated nut; and, on the front spar location, you will want to use aircraft bolts similar to the rear spar bolts with castle nuts rather than the pin secured with a hairpin (which is not designed to carry any load at all) used for keeping the pin in place.

Best bet is find a kitfox with an owner who will let you examine these points on the aircraft...plus you will end up doing some minor engineering with the hardware needed.
