Proper belt routing 5.0L Tbi

I recently got a used upper fan shroud to replace the cracked one on my car, and noticed the routing decal on it is different than the way my belt is routed on my engine. My original routing decal is missing, but the new shroud I got came from a car with the same engine as mine, so now Im thinking maybe my belt is routed improperly. Could someone please take a look at the drawing I made below and tell me which is the proper way to route the belt?

The decal on my new shroud shows it like image A, but the belt on my engine is routed like image B. Will either way work, or is my belt put on wrong? I have a 91 model firebird with 5.0L Tbi and A/C. Thanks.

I don't know if it makes a difference, but mine is routed like yours. If it fits both ways I'm assuming it really doesn't matter because all the pulleys will be spinning at the same rate no matter how you have the belt routed.

The left looks like mine with air pump delete pulley. the right looks like the normal routing(before air pump delete).

Thanks for the replies guys I guess my belt is ok then. Mgilorma, is there any chance you could take a closeup picture of your belt routing decal so I can make a repro of it to put on my new fan shroud? I would like to have the proper routing shown on the sticker since Im a bit of a perfectionist.

Either is fine, the water pump will flow in reverse with either routing.
