"I have a '57 Fairlane 500 and I would like to install the factory dual points in the distributor.  I have the NOS original dual point breaker plate.  I believe dual points were only installed at the factory with the supercharger.  However, I have not been able to locate the points and condenser that fit it.  Per the 1949-59 Ford parts book, the two sets of points each have different part numbers, and those numbers are different than the part # for the single points.  But the points from the std single point distributor will fit on the dual breaker plate in one position though.  Which set of points will fit the other location?   

I would appreciate any assistance you can provide in locating a supplier for these obsolete parts.  I've tried several antique or obsolete Ford parts catalogs, but no luck.  I know these were limited use parts even when new and are super rare today.  But where do F-bird owners get those parts to keep their T-birds original?"

Tim not sure from over here but i am thinking Bosch GF82V points, they are curved like the 57 type points and may fit one location, i dont know what the factory had in mind at that time, maybe opposite hand set, either way, locate condensor outside housing and see if another set will fit, if the attaching holes line up good! and may require the  locating pin under base ground off or plate redrilled,  they usually fire about 8 degrees apart. Just a old time suggestion! Best regards bill.

Those look like the same points to me.  '57 and later.
