XJ-SC Hard Top – are these fittings correct?

Hi Experts, feeling really chuffed to have recently picked up a Hard Top for my Cab.  The thing is that this hard top’s fittings seem a little different to the others I have seen in pics.  I’m based in Australia, so anyone in Aus that has a hard top, can you confirm whether these clips / fittings look normal?  Also, there is a clip at the centre top of the roof.  I have no idea what this attaches to, as I’ve never seen this before either.  Any tips, photos of the attachment clips that others actually have on their hard top would be appreciated.  Thank you, Adam
