Transmission drain plug replacement help

[danehboi]

Hi all, recently striped my transmission drain plug. I'm now chassing a new one but can't find any info or plugs on Google. I know I need a magnetic drain plug and the one on it is a 1/2 drive that's tapered just can't get the thing out to measure.
Does anyone have a good website they order from?
What is the size plug I need? and do they differ in sizes between patrols and navs.

Any help if very much appreciated.

I've got a navara d22 2006 ZD30
