Air box removal

[mark-tda4s]

The starter motor on my 2003 Tamora is starting to get a bit sluggish. I'm fairly new to the speed 6 but quite handy with the spanners so want to save a few quid by replacing the starter myself!
I've tried to remove the airbox top by removing the 2 Allen screws and the 2 clips but it won't come off. There seems to be something else holding it that I can't see?
I've also removed a 6mm screw holding the bottom section at the front thinking that they may come off together but still nothing is budging!
Any clues what I am missing?

Got it! Cheers! Starter now off without skinning knuckles.

I have ordered a starter motor from TVR parts, however, the short motor I have removed is 1.4kw I believe. I've actually ordered the 1.7kw which is 20mm longer and doesn't have the 2 screws on the end to mount the clutch bleed pipe and fuse holder. I'm assured it fits but need to do some fabrication work to mount the bits!!! I've also ordered a new fuse and holder for the sake of a fiver whilst everything is out. The longer 1.7kw starter was £100 +vat which is £35 cheaper than the short motor which I find odd but being a Yorkshireman, I'm not complaining!
