Doors break down to 73-76 and 77-91, you want the 77-91 (only year power was availible) Any door panel will fit this door from 77-91 and power can be added, 73-76 panels won't fit this door.
Hoods, any of them will work, but the 79-80 has a raised portion on the leading edge where 73-78 were smooth.
Fenders are the same from 73-80 as were the inner fenders.
