Lug nut size help

[Evolution69]

Hi
Ive picked up some cool old ansen sprint mag slots 15x10 rear and 7's up front, hopefully pic uploaded

I believe i need "shank" or "mag style" lug nuts, 
Ebay is a mind field with made in china parts

So decided to look for old vintage shank lugs, ive come across 1/2" and 7/16" and not sure which ones to get?

All so the original lugs on my charger have to be replaced anyway, so i can change these as well while im at it, any Recommendations?  Just want to keep the old school look "round top"  instead of opeln lug nuts,

Oh and is it ok to "convert' to right hand thread or keep it left

Thank you

Good day Evolution!

- Yes need Shank style, see photos
- 20 x 1/2 is what you want
- The old American Racing Slots, which is what you have, use the shank. the new Ansen wheels have a cut out so you can safely get away with Acorn type. That is if you have the newer ones as well (Ansen never made 15x10)
- YES! ABSOLUTLY update from those dreadful threads...but changing those out are always a pain
- Nice choice on wheels, they'll look great but you'll have clearance problems so will beed Air Shocks or something

I'm confused. Am I reading this wrong? The first picture above has the cutouts (over bored hole???), so lug will not be shank style. I'm I correct on this? If not, let me have it.
The second picture uses shank style lug nuts. This wheel is what was called ''Unilug". Fits more then one diameter with five bolt/stud pattern. See the oval hole in the wheel.

Hi yes you are correct, the first pic has holes that are not "flat"  they have round cut outs, the second pic has cut outs for washers, i would all so call these multi lug rims

We call them tapered or acorns in my neck of the woods.
