Wrong stihl part?

[TimberMcPherson]

Hiya, dumb question time, I was after a piston and barrel for my ms200/020 and got one but its looks different, on the cylinder it has 40zd34 and on the other side 1129. There are alot of numbers on the box including 1129 020 1202.
Does anyone know the part number for the piston and barrell to an ms200t?

The numbers from the box look right by this:

The 200T is 1129 020 1202 and the 020T is 1129 020 1201. Since there is two different numbers I would guess they're not interchangeable.

AHHHH that would explain it, I just figured that there were the same. The only difference that I can see is kinda major, the barrel has ports on the bottom walls of the cylinder on the new part where the old one doesnt, Guess I will have to get another one. Thanks for the info guys, saves me alot of head scratching!
