call and ask
I think the only difference in the end is what fittings you want, STC or JIC
I think if I had a SD I would swap it to JIC but have no experience with the 'quick connectors'
there is the antidrain back check and the fittings but just call Gary. You'll likely have to leave a message but he'll get back w/ you. He called me back COB the same day I left a message.
