Bloody mekanix - I'd check that they've put the top arm hinges in the right places then too - ie. my Whiteline C/C Kit had two front and two rear hinges made of different material (two are of a harder purple material vs the others of a softer red material - can't remember now which are front and which are rear tho) - the mekanix that fitted mine had them a*** about which caused the softer ones to collapse after a couple of months.
