I may be able to help you out. I've got a set I can offer you - they're new & never been put into hubs. See picture below. It looks like the average cost is $6-6.91 each...I'll ship for $50 within the US and can have them out within 1 business day after PayPal.
I can dig through my stuff - I'm quite certain I have used steel lug nuts. If I do, you can have them free with purchase of the studs.
