hello, I went to order some oem replacement parts and for my model year, 1999 sportsman 500 awd., there are three model numbers listed, none of them match my vin # ?. i am looking at rocky mountain, they list :A99CH50AA
A99CH50AB
A99CH50AC
My vin # starts like this, I left out the final digits that i figure does not matter.
4XACH50AOXAO..... ?????

I am confused.

 

What are you confused about? You have a 99 and major difference between codes are the color,some decal differences,wheels,etc with AC being the Remington Special edition camo color.

 

I did not know if the different code variations affected parts . i did not know what they meant, that is why i asked. these machines are new to me. thanks for the edumacation.

 

Many major parts are the same. It's just when you want specific plastic parts,decals,etc do codes come into play.
