i reckon you have a 2003 -04 model frame m8,if you get the frame number it should be around the BB shell and phone orange then they will comfirm it if you give them the number,i have a 2002-03 LT and had to do a bit of research myself and after wracking my brains they told me straight out,i dont think yours is any older than 2005 though m8.
ive noticed a lot of people listing patriots at no where near the right year on ebay a lot m8 and i can tell you now that's not an 06,an 06 has a more rounded swingarm at the pivot area,i think orange changed it on the 05-06 model,and the shock mount between the top and bottom tubes is way more akin to an 04,i'm after another one in a 14inch so i'm looking all the time fella,i'll have 3 then(14,16,18inch)
