Corvairs were always favourites of mine (even though I never owned one). I thought by '64 that GM was using alternators, yet the car in the picture clearly has a genarator on top. At first I thought it was the starter, but it is mounted (of course) by the flywheel.
An oddity of the Corvair is that, with the flywheel at the forward end of the engine, which is mounted behind the transaxle, the engine run in the reverse direction of most ICE engines. Chev engineers wanted the flywheel rotation from the front of the car to be the same as their other cars, but since the flywheels of rear-drive cars, which is everything else GM made at the time, are at the rear of the engine. Consequently, the camshaft and distributor turn 'backwards' as well, confusing many mechanics.

Good info, Barrie. GM didn't put an alternator into the Corvair until mid-1964 and in the model year '65 when the new-generation came out, with its significant engine changes. This car is an early '64 (don't recall the month). The owner told me that it came with everything, but that the engine was sitting in parts in the back seat as the previous owner had pulled it to overhaul it and never got around to actually doing anything more than taking it apart. He did do a beautiful job on the body, paint and soft top restoration, though.
