I've found a few of them on Ebay. Seems that these generic items have a threaded connection. I have no idea what the pressure settings for the overboost switches used by Saab are, but there are a couple of these 'Hobbs' devices specifying 15 psi which sounds about right for an 8V non-APC turbo engine, though I'm open to correction...
