I have never parted or owned a 63 Tempest that had the top hose on the driver side(left). Don't think they ever came that way. The Chassis Shop Manual states that 4 different radiators were used on the 63 Tempest cars. They may be identified by the radiator code stamped on upper inside right corner of top tank.

Code 151--195 L-4
152--195 L-4 A/C
154--326 V8
157--326 V8 A/C
