Reaching out to the experts, I believe I have the original set of rims on my 1967 Shelby mustang and I noted that the Lugnut hole seems to mushroom out because of the current lugnuts that were used on the car, is this correct? (yes I know the tires are old and they will be replaced when car is running)
Thank you for your help

The picture is a typical 67 Shelby Magstar lugnut .
this may help...
Hmmm, the other photos didn't upload. It's for a Kelsey Hayes Magstar.
Looks like the same as the bottom lug nut in the reply #2 - the S7MS-B 3/4", and that Bob suggested in reply #1.
does it use/fit a 3/4" socket?
Great. Is the lugnut opening suppose to look so "mushroomed" like in the picture?

No the lugnut opening looks damaged. Maybe a non Magstar lugnut was used some point in the past that caused the damage. The shoulder of the Magstar lugnut should fit all of the way into the hole leaving the contoured edge to make contact with the corresponding contour edge of the wheel opening . My concern would be that the hole has been damage in such a way to not let the guide shoulder of the lugnut to go down into the hole all of the way. The lugnuts could have also been over tightened to cause damage sometime in the past as the lugnut is stronger steel compared to the softer and weaker aluminum of the Magstar wheel center.
That is what I thought. Thank you all for the info. Won't be my last question so I appreciate all the info/help.

Hi,
All good points made so far
Please make it a promise to properly torque all lugs to 75-100
ft lbs and check all the lugs again after the car is driven. Failing to do this can be dangerous!! Do not risk a loose wheel.
Regards R.R
Yep. At the beginning of the each driving season I double checked/torque on all my suspension items on my Tiger and check the Lugnuts before each drive. I used to have powered-coated American Siliverstones (Real magnesium Wheels) on the Tiger that used to back off on the lugs. Because being mag wheels, I retired them and now they are wall art.
