Align pop up headlights with bonnet

[trace1967]

Old headlight covers/tops (not plastic covers) are rubbing bonnet and bit of bend in one due to me fitting new lamps last year. Just got a pair of black headlight tops off ebay for £30 inc del. Can someone please tell me how on earth I can get these headlights aligned with the bonnet correctly doing it by myself. How do I take off the headlight tops also?

some pictures would help me to align the lights up, the corners are rubbing slightly on bonnet.

Have tried that, no luck, want to get them flush before fitting new lids.
Help! What screws do I have to undo to move the whole headlight. Not the lamp, I mean the whole unit is out of line with bonnet and the other side too.

On the passenger side its the curved corner hitting the bonnet and on the drivers side its the lower pointed corner neareast to the badge on the bonnet.
