I am replacing the motor mount by the radiator. The car is on jack stands, and the engine is jacked up with floor jack. The oil filter adapter is out (I'm replacing its gasket) and I've taken all bolts out of the motor mount bracket. Radiator also loose. Lower mount nut is off, can't get the upper mount nut off. What now?

You need to remove the mount with bracket from the vehicle, and install the new mount to bracket.

Use your jack stands to support the body at rear of the frame. Remove the front two subframe bolts, and use your jack to lower the frame. I even pull the frame down a bit further and place a deep socket between it and the body to keep the space. Remove the fastener that secures the brake lines(plastic bracket) to the frame, you will need the lines loose. Remove the top two bracket bolts at the cylinder head, and the two lower nuts along with the studs. What you want to accomplish, is to be able to lift mount and bracket, to clear the lower mount stud from the frame. Rotate the mount/bracket clockwise until the top portion clears the opening, and you should be able to withdraw mount and bracket through the gap, with some persuasion. The top of the bracket will come out first, and the rest will follow. In some cases you can use a jack to lift the front of the engine some, if needed, for more clearance. As long as there is a block or something between the frame and body, it should not rasie with the engine, as it would with no spacer. This is about the best direction I can give, based on my visual recollection of how I service the mount.
