are those EDP black pieces repro? could be a problem .... you can't expect the hood to fit until the fenders and front pieces do, it looks like the top tie bar isn't bolted tight on the pass side, how does the grill fit?
looks like the driver fender needs to come up at the front [to narrow the gap at top rear] - the pass side needs to come in at the front to even the gap at the cowl, a thin shim at the back top might do it, or that odd cup at the back that the fender bolts to might be out of place a bit, did you work on those?
the place to start is the rad support, there should be rubber pieces and washers under it that will shift the fenders up or down at the front, so down or up at the back - also it mostly controls the spread of the fenders at the front, and it determines the position of the latch panel at the front, which will affect the position of the hood - it's a pushme pullyou situation, rarely can one piece can be shimmed and fiddled to fit until they all fit .... frustrating at the best of times

also you need to keep in mind that the fit and finish on these trucks was "good enough" from the factory, not perfect

and if the cab was off, the mounts there will affect the fit of the front
