and i think it would be a good idea to make the lh threads also,
remember 10 lug nuts per car are lh for all 1970 + older, thats a large number of vehicles. there were lots of b-bodies made 67-70 + allot of 70 e-bodies too
there were variances on the bumps on the lug nuts, if you want to see some more let me know,
ive got some lunch pail lug nuts circa 1970-1972 if youd like to check them out
