I reassemble piece by piece, start with the core support then inner fenders then fenders. One common oversight that people make is forgetting the shims between the inner fender and the cab brace. It will ruin your panel alighnment between your fender and door. Loosely attach your inner fenders at the brace, hang the fenders (after the doors have been alighned) and then shim the inner fender as necessary.
