FYI - not sure if others are aware but Ron Frances sells an OEM style backup switch connector for the T-5, #PG-055 w/9" leads, $17.00.
(This is not the same as the two right-angle single connectors that are available from several sources)
65 Fastback, 351W, 5-speed, 4 wheel discs, 9" rear, R&C Front End.
