Gonna look a bit weird my 550ex hooked up to my old Nikkormat, but it will work.
The nikkormat will ONLY tell it to fire at the correct time.
It wont relay any ttl info, thats why you need to use the EX's in manual mode.
You will need to know subject distance & guide number for the flash in question because the 550/580's have no thyrister to quench the flash.

I would recommend a vivi 283 except it doesn't swivel. Only drawback.
