"New Departure Bearings" has been in business since 1889 and is actually the oldest division of General Motors. "New Departure" is a quality bearing manufacturing conglomerate. DD
I stumbled across this older thread while GIGGLING -
The above description(s) of the F-CODE DUAL POINT DIST(s) are correct.
There was a FORD SPECIFIC DIST and a BIRD SPECIFIC DIST (TACH drive).
As they were released for the 1957 model year, they used the single breaker plate style (FOR dual points) B7A 12151-B and the condenser was mounted outside of the DIST HSG.
Cataloging does not indicate an E-CODE DUAL POINT E-CODE DIST, either 270 or 285HP.
