Any known original '64-65's with A/C and 4.56 differential ?

[Wayne M.]

In theory this would apply only to solid lifter L76's and hydraulic '65 L79's [up to ~March '65 when the 4.56 ratio was dropped for the 350hp, per Chevrolet Service News]. By 1966+ GM came to their senses and restricted the stump-puller gears to select big blocks.

Hello Wayne,
I know of a 1965 Nassau Blue with blue vinyl coupe. AQ rear axle code 4.56. The rear is date late 1964.
365 hp with air conditioning.
This the only one I know of this configuration.
Regards,

Thanks Drew -- my '65 C60 L76 has 4.11's (AP 9 17 64) and I thought that ratio was weird enough . Original owner said it was a "belt tosser".
