Formula S Long Lug Nuts

I need 5 right hand thread lug nuts, but do not want to go to Mitchell Motor Parts.

They are a bit spendy, aren't they? I bought a complete set -10 LH 10 RH and ran them on my 14 inch Formula S hubcap-equipped 65 Valiant 7 or 8 years ago. Still have all 20 even thought the car is long gone. May part with them but only as a complete set.
