Welcome Michael!
The front end swap should be pretty straightforward. The mounts at the lower rear of the fenders changed, but I think the hood to cowl profile is the same until '91.
Hopefully someone will correct me if I'm wrong.
I know that at least one of our members has done it (Shaun from Florida)
Gary and I were just talking about the radiused rear wheel arches and flat tailgate of the bricknose trucks.
