if it does not have the right fittings ....can't you just run adaptor fittings? or cut the heads off of your own line and put the matching fittings on and reflare them?......or put the matching fittings on with a chunk of line with fittings on the opposing end to union into your existing fittings or run a short stretch of rubber line.
seems like there are a few options for you so I wouldnt call yours and garys possible deal off just yet.
