The 08 pole is identical apart from the cast alloy top end, thats where the difference in length comes from as LBE said.
If you are serious about any kind of decent throw from your steering, replace the top cast section, or buy a pre 08 pole. I have an 08 pole and an 08 steering cable on my junk SN (just to make the steering work) and I find it hard to even do nose stabs! Every now and then I can land a roll, but you need a lot of rider input. Steeering throw is your friend...for real!
