Glad to be of assistance
Maybe I read the tyre specs wrong - I'm never really sure what those numbers mean

The wheels are 'Challenger' by Performance Alloy Wheels - they are a continuation/copy of the 'Globe' or 'Daytona' used on some of the GT Falcons.
I quite like them because to me they say Ford, but ironically Ford was 'inspired' by the Ferrari Daytona according to this website:

(I have posted that link before, you have to scroll down about 5/8th of the page to get to the bit about the Bathurst Globes).
To save you some clicks here are the images

They're in SA and don't retail, however when I rang them they told me where a nearby retailer was.
They offer steel inserts (washers) for the nuts to tighten on. From memory the 15x10s you see pictured were approx $256.00 ea.
Because they're cast you don't get much (if any) choice of backspace but fortunately mine were fine for my RMC with Jag rear.
good luck
