HiYa Moondog,
There is a mob in Sydney, well, NSW some where
I think the name is austwheels/ozwheels something like that.
They make a halibrand replica cobra wheel, I know they have 15" and 16" but I dont know about 17".
They make bolt in centers and welded in centers. The rims are american supplied polished alloy, with a huge variety of widths.
Quality is quite good, someone in NSW made a pattern for the center and this fella now manufactures the wheels and a matching polished alloy spinner. They were about $1700.00 for a set of 4
hope this is of some help
