If not, any suggestions on reinforcing the back of the window guard with something other than plywood.
Thanks for any help with this...
I don't have that model to compare but I can give you an answer based on knowledge based on how such things are done. To hold in such pins there will be one of two ways it was done. There might be a very small set screw in a fixed knuckle of the hinge that is putting pressure on the pin. If so then removing the set screw(s) will let the pin be driven out of the hinge.
The other method of securing the pins is they do an upset on the end of the hinge pin, meaning they hammer on it to make the tip wider at both ends so that it won't slide out. A bit of drilling or grinding can remove that upset wide spot at one end of the pin so that you can then drive the pin out of the hinge. You only need to drive it far enough to grip onto the pin with pliers so you can pull it out. A steel nail small enough in diameter to fit into the knuckle will suffice for a drive pin if you don't own a set of drive pins.
For either situation I would suggest before you start work to put some spray lubricant on the hinge so that the pin is easier to slide out. Be sure you keep the hinge knuckles supported in alignment to each other on the ends to keep it prevent binding at the knuckle joints which would make it more difficult to remove the pin. Small steel spring clamps will work for that. Those are easy to find at hardware stores.
