What was the stock rear wheel and rim size?

That's the correct oil tank mount tab then. Only west coast Hornets had the large oil tank. The frame is also specific to west coast model, as the oil tank saddle of the frame is different.

Rear wheel size is the same as all other A65/A50's: Jones 42-6361 WM3x18 with a Dunlop Gold Seal K70 tire. That tire is still available.
