I don't know about the old orange heads but the low profile orange heads had a FG537 and the black heads had A536, A538 and A540. Harvs could make one up for you. If you are so inclined you could take a A440 head and slide the units over and put a fifth unit in the center and get new snapping roll drive shafts (one for two rows and one for three rows) and new center tin. Why not go with a 8 row planter and 4 row head to keep things standardIJ
