In profile the OZ type has a pronounced kick-up then a flat outer edge which is folded under. I'm aware some people have tried to make the Oz type with various degrees of success. The problem is the very narrow edge that makes it difficult to fold in a standard metal folder.

I have one that is coming off my mini was going to just rip it off but sound like no one is making the Aus version is that correct.

There is four welds on the upper side that appear to be doing nothing.
However there is a lot of spot welds running along the gutter holding the rail in place.
I will take some closer pics to check out the profile and post them
Thanks for the information
Cheers

I have replaced the drip rails on my '66 mini due to excessive rust between it and gutters.
These were made at TAFE (when they let people do courses). I am not a trades person and have limited experience with panel work but it was not hard.
Use old strips for guidance: start with some flat strip;
-bend a 5mm return along one side - it will need to be dressed flat by reversing it in the blades of the brake (or by careful hammer but that leaves marks). This is the part some said was hard/ not possible but it was easy.

The "kickup" winabbey mentions is a shallow v-groove using a swaging jenny.
The full length is slightly bent to give the correct angle of the drip rail.
I made 2 shorter lengths of the same profile and used a "stretcher/shrinker" to get the turn-in at the front of the gutters and welded these to the long lengths for each side.
Rather than weld these to the underside of the gutter, I used auto glue to help stop water getting into the joint in future and give a nice seam filler.
