I'm not so sure about the sales pitch.
I fellow I deal with on regular basis asked my opinion about it. He was going to make an offer...

Door sill plates are wrong yr. '78-91 plates
350 emblem is off the grille so at least grille has been off.
Spare tire carrier is missing and no sign of it ever being there.
Paint seems like too much orange peel for factory paint and not one spider web swirl from it being washed over the yrs.
Underneath looks like 144k miles.
Maybe its just me but it just doesn't look like a 44k truck. Its nice, just "too" nice to be all original.
