24V to 12v change over

After looking at how hacked up the dash wiring is in my 85 M1028a1 (Military K30) and needing batteries any way . . . How involved would converting the 24volt system to 12 volt? Anyone here done this? Engine harness change and dash wiring change plus starter. Anything else? Found a complete GMC 6.2 one ton auto 3500 in a yard , should have everything for a swap. Note, this K30 has 2 100 amp alternators, I suppose they would have to go to also. thanks in advance
