AIR CONDITIONER ORIFICE TUBE LOCATION

I Am Replacing The A/c System In A 99 Ford Ranger (4.0 V6), But I Don't Know Where The Orifice Tube Is Located. I Can't Find The Old One...

Where Is The Orifice Tube On This Vehicle?

I Have A 88 Ford Conversion Van, 300cid 4.9l Six Cylinder With Front And Rear Air And Need To Replace The Ac Compressor And Orifice Tube. ...

Can You Tell Me Where The Orifices Are Located In The Lines And If There Are One Or Two For This Van?
