Your car has to have the double row for three reasons:

1. I've also read that in 1984 they all came with the double row.
2. I can't imagine a dealer / independent would do a timing chain replacement and not convert to a double row.
3. All of the 380 SL / SEL's that had the single row that weren't converted have all by now probably blown up.
