the standard length bridges should suffice unless you've installed some wacky coolers or you're running cf on an x58 (in which case the longer bridges should be with the mobo accessories).
No the normal one will not fit it's short. I have a M3A97-T Deluxe. I got an open box one because my Gigabyte DS4 has failed 4 times within the last 8 months and didn't have the funds to get a new board..so I got an open box and of course the open box didn't have the bridges.
