Our staysail sheets go from clew through a stand up block on the coachroof (which to me seem undersized if the ss is used as a storm jib) to a forward car on the genoa track then straight to the secondary winch. It was not like this originally and we scuffed the fiberglass on the cabin top. So we just got new genoa cars and used the old ones for the staysail sheet, which get less forces applied than the genoa cars. It does not really matter the forward/aft position of these cars as their position does not affect the lead angle of the sheet, so you can place in a position that is best for a good lead to the winch
