ENO LPG Stove 8mm olive fitting - need help to replace

I over tightened the nut on the 8mm olive and cracked the nut. I'm having a hard time getting a replacement or even the bits to build another one. So far I've tried local bbq centres, two gas fitters, Gameco in Sydney, the local and NZ distributor.
8mm female olive, female flared 15mm BSP the other.

Any idea where to buy another?

I just googled 8mm olive nut and got multiple options.

Thanks for that.
its imperial BSP on one end and metric on the other. I can buy all the bits and a flaring tool and make it myself, ( and probably will have to) but I was hoping there may be an easier way to buy one off the shelf if possible, ideally tomorrow ready for a weekend on the boat.
