Left hand thread Steam Rad Bushing

Desperately seeking an 1-1/2" left hand threaded x 1" right thread bushing for an old steam rad.
It's a tight fit and the left/right nipple approach is a last, last resort.
I'm In the Phila area and appreciate any and all suggestions for sources.

    When we can't find a left-hand-thread bushing we screw in a L-R nipple and take it from there.

    Probably those left hand threaded pieces are available from McMaster-Carr.--NBC

    I have a 1-1/2" left-hand/right-hand internal radiator nipple. End-to-end length is 1-1/8". Will that do?

    Thanks Gordo, but I'm dealing with a bank of wall hung rads that are very close together. If we go with anything but a bushing, we'll have to remove and rehang the whole mess. However, I am getting closer. Shafter Bros. in Montreal carries a !-1/2" left x 3/4" right bushing. Thanks again, Wallies!
