Can't figure out what kind of lug nuts I need...
 

I bought a new set of wheels, Enkei Apache V's and I can't figure out what kind of lug nuts I need to put them on my '79 Rx7.
I was looking at picking up Muteki open ended lug nuts but I'm not sure if they will fit.

Those are the lug nuts I'm looking at. ^^^^^
Their specs:
Material: Anodized 1008 Steel
Weight: .9oz
Size: 20mm diameter x 21mm height
Adapter: 6 sided 17mm socket included
SOLD IN SETS OF 20

I'm not sure what seat I even need.
I'm running in blind can someone help?
Let me know what you guys need from me and I will get it for you ASAP.

Here is a pic of one mounted on the car.

I'm pretty sure you need the thread to be 12x1.5...NOT the 12x1.25

Take one of the wheels into a tire shop. Between seeing the wheel, and knowing the make/model of car, they'll be able to tell you exactly what you need. They'll probably even have what you need, at least as cheap as you can find online.

I don't know if you have Discount Tire shops down there, but they've taken great care of me in the past. Good luck. :)

I have one right down the street.
I'll try that later this week.
Thanks

Alright, I took them down to discount tire and they told me that the required lug nut seat is an acorn and I need the 12.5 thread for the studs.
Next week I'm rolling on down to a rim repair shop and dropping them off to be restored should be on the car permanently in a couple weeks.

Do you think a 1.75 inch over all stud length be just fine?
