Advice on H5 Headlight installation

[Slfan]

Hello,

I just acquired a nice set of H5 headlgihts for a US spec 1979 SC with the sugar scoop headlights. As these headlights do not include trim rings or mounting items, can somebody please advise me on what parts I will need to perform this installation?

I am figuring I will need mounting screws, trim rings, headlight relay, etc. However, I would GREATLY welcome any of your advice or guidance on what parts I need to purchase and any modification I may need to do in the bulb plug or else where.

Regards,
Angelo
