The Helms manuals are great (Factory Ford manuals) I use a 96 set that has been a lifesaver over the years

The Helm website can be a pain. For model, put in F-series instead of the actual model (F350, F250, etc.). You will notice other manuals as well, but I just listed the basics. At a minimum, get the shop manual set and the EVTM. Powertrain/Emissions Diagnosis is good if you have the diagnostic capability. I prefer paper over CD’s, but the CD’s do contain the whole enchilada (Shop, P/E Diag, amd EVTM). It’s much easier (I think) to flip around the paper versions and find things. Hope this helps! Cheers!
