Honestly, the only decent replacement method is to get a new one, or one off the very same vehicle.
New isnt always cheap, but it will probably never go out ever again while you own the truck.
Used is always suspect.
The calibration is different for each model, and drivability will become a new issue to deal with if you just toss something "that fits" in the rig.
Airflow meters need to be handled carefully because you can damage the resistors by banging them around.
Oil sometimes gets on them and they dont give a good signal anymore, so look into that possiblity on a used part. (your original or otherwise).
Use electrical parts cleaner.. Carburetor cleaner is too strong and may damage the material on the resistors, or the Plastics of the Airflow meter.
Hope these tips help.
You wouldnt have a flow meter if you dont have F/I?
Should be a Map sensor, and if Memory serves, a TPS (throttle position switch) but thats all on Carbed models?
Strange.
