6.2 diesel tach signal from alt?

[plugugly]

trying to determine what alt will swap into my 1987 6.2. I need the p or w terminal. Ive tried an alt from an impala and 90's chevy. They both came with serpentine pulleys. I was hoping to swap my pulley onto these, but it does not appear to be workable as the impala alt has an external fan with integrated spacer that wont work the the vbelt pulley and the 90s cs144 alt fan setup seems pressed on or somehow integrated into the shaft.

Does anyone know of an alternator that would have the P or W terminal that will swap into a vbelt setup?

I had a whole reply typed out and then realized I missed dthe part where you said you can’t swap the pulleys. Good luck!

Why not just buy a replacement 94 amp alternator for a 1987 6.2 and be done with it?
