radiator bushings

Ive got a couple steam radiators that I want to convert to hot water for a customer. After cutting out the plugs on one side I found they have left hand thread. Does anyone have a source for L-R bushings so I can use these?.
Thanks in advance.

    Pressure test them before you do any further work on them to make sure they are usable.

    He can't do that until he finds a fitting for the left hand thread.

    Don't know about bushings but McMaster Carr has left hand right hand threaded nipples. You could put a nipple in the radiator then a reducing coupling concentric or ecentric as needed
