These are real Dodge Viper lugnuts. I have L.H. & R.H. a couple full 20 pc sets, mix or match. were $30 plus shipping, NOW $18. These should fit big Buicks. These are made in the USA. I made them.
You have both left and right hand threads? How deep are they drilled/tapped? These might work for the scout..
Yes, both L & R. or all of either one. Depth mics at 1.080, so with bottoming tap, I would say around 1" thread depth. O.A.L. of lugnut is 1-1/4"
