About 4 years ago I've bought a Gascraft BBQ at The Warehouse. It works fine, but the flame tamers have rusted through. I've contact TWH, also various shops on the internet, but nobody stocks the size of flame tamer I'm after.

On Amazon, I can see universal flame tamers that can be adjusted to size, but can't find them here.

Only one in NZ that comes near is this one, but the size I need is 351mm x 118mm so probably some cutting is involved... And to spend $30 + shipping on something that doesn't fit, seems wrong to me.

I'm now thinking to buy the Amazon ones using Youshop but that will cost in total about $60 for 4.

Don't want to buy a new BBQ as other than this, it's perfect.

Any other suggestions?
