Couple quick questions as I am trying to wrap up the blazer hatch

I didn't disassemble any of this so that is the reason for the questions .....

1. What size is the screw that goes into the gasket cover plate - the holes appear to be threaded.....?
2. What size screw holds the hatch handle on ? I have a new handle from MotorCity K5 but the screws/bolts that come with it are too large for the factory nuts that are welded to the backing plate
3. Do I have the correct orientation for the hatch latching rods ? Anyone know the size of the latch bolts

Thanks !!!
