If I was in a pinch, this is what I would do... Ultimately it will be determined by your experience and your skills...
I want to think that both sides of mine are more or less trimmed the same. So if you have the Left side, remove it, and make a cardboard template., take some measurements and then put your template on the part you want to cut. make it longer than what you measure at first and then start sneaking up on it.
I would NOT use a reciprocating saw like a jig saw, or scroll saw, it may seem to be the easy way, but the reciprocating action may cause the plastic to crack, and you do not want that... Ideally you want to use something like a Band saw, or a hand saw (like a coping saw) The coping saw may be really ideal as it should cut reasonably quick... Once done, take a file and clean up your edge. If you use a coping saw, you may have to cut out sections as you go to clear the frame of the saw...
