If the 2011 7.5 is anything like the 2010 or 2011 7.3 FX, you won't be able to fit 45 mm mudguards (without cutting them to accommodate fork width) on the 7.5. The fork's too narrow for them. I just had a look at my wife's 7.3, and the mudguards are 37 mm at most (it's a fiddly measurement).
When I took the 7.3 to my LBS, they said that 45mm was the recommended width for that size tire, but also said they couldn't fit them (unless I was willing to take the risk of them breaking when they made the cutout). I opted for narrower ones, and they work fine, if outside recommended dimensions.
Regarding the rack: my wife has a similar looking (but disc brake specific) version of the tortec. It's fine as a rack, but it sits rather high, which makes it look a little clumsy. I've got this one http://www.evanscycles.com/products/...2?query=120868
(on my 2010 7.3) which sits lower, and looks more like it was made for the bike rather than added as an afterthought.
