This might be a little late in posting. I own a San Jose K code date code 27G # 5R07K 102379 Hood was a 64 1/2, headlight buckets were not 45ed, had the pre 65 vents in radiator support, had 64 1/2 horns, had the early style front fenders, had the threaded pcv valve and brass fitting, had the plug pressed in the timingcase, Had an ALTERNATOR rather than a generator, had muffler behind the axle but had resonators and gt trumpets (I don't think these were factory) also had factory exhaust brackets near the tailpipe flanges like a single exhaust both sides and brackets at the 10 and 11 inch positions from the shackle with large clamps like the arvinode system around the resonators, had factory K stamped vin in axle tube?- stamp matches the engine block stamp exactly, had 15 inch wheels, early style carpet. Mine was definately a transition car. I suspect it was built around August 10-20th 1964. My former Allstate insurance agent Niel Witcher worked on the San Jose assembly line and told me he remembered working on only 2 or 3 k codes in the 2 week period of the 64 1/2 cars also there were a few hipo fairlanes built in that period. At least that's what he told me.
This lends credence to the theory that there were no Generator San Jose K codes.
