Dzus fittings on goblin hoods

[Amack1970]

I'm looking to replace the 2 dzus fittings on my hood. They've been ground down by curbs, speed bumps etc. I found some made with a allen head instead of the straight blade channel, but it looks like there are multiple sizes. 5/16 and 7/16. Does anyone known what size I need?

I used these: Dzus Button Steel Allen Oval Head 5 Pack Dzus Fasteners Quarter Turn .500 7/16

I believe I measured them at 7/16 .500 grip length
