The bracket looks correct to me and the rubber bushing does not.
On both of my A65s, I gave up on trying to get that mount "as original", and reengineered it. If the i.d. of the bushing is 5/16", you could cut the o.d. down to fit the oil tank. I'd also suggest a rubber washer between the oil tank lug and the frame.
