The radiator to condenser insulator/spacer located at the top of the radiator on each side (#6 in the diagram) might be stuck to both. Here is the link to the image I am referring to:

Also, the condenser might be stuck to the rubber radiator mount (#12 in the diagram) on the bottom of the radiator.
One last thing, there is no need for a double post on this forum.
Good luck!
