The solid steel lugs on some early rrc will work. I have a line on set if you want, they will need painting.
$3.36 is pretty cheap. I have a bunch of original lug nuts before they made the stupid capped versions that suck. They aren't pretty, ok, three are like brand new, but the rest look like 20 year+ lug nuts. But they have clean threads and will work great. Find my contact info at http://www.chadmanz.com/parts.html if you want some of my nuts.
Just bought some lug nuts from LRDirect. One was a direct replacement, but I went ahead and bought 5 spares just in case. $3.36 per lug nut. Pretty cheap.
