Does anyone know where exactly the orrfice tube goes ? I want to replace it but i cant find the old one in any of the lines.

 

And the car is??

 

sorry pete was in a rush. its a 95 z lt1. i think i figrued it out . i got a reciever/dryer for a 95 but the part didnt look the same. i ended up getting one for a 94 and its idenical. so if i have a 94 ac it shouldnt have an orifice . right/?
