Welcome to TP Ian
That should work, but there is the usual question of higher trigger voltages of older flashes damaging modern cameras. You can check it with a volt meter.
For complete safety, and wireless triggering, get a radio trigger such as the Yongnuo RF-602. A guy on here, Flash In The Pan, sells them for £28 a set, post #2 on the link. Check with him re compatability but they should be fine
