The oem stay is a no-go.
Thought about it for mine but the bonnet twist a lit under its own weight. Not like It
On my track car I fabricated a nice long aluminum pipe (14mm in diameter) with one rubber end and another plastic pointy end.
The pointy goes in the square hole near headlight, the rubbery end goes in one of the recess of the bonnet, where oem got those squarish holes.. it hold well and its handy when working.
Yes you have to carry around if you need it.
I've seen some guys use those premade telescopic curtain bars.
