I recognized it right off? Too bad there are no dimensions on it though?

FIFTEEN.....DOLLARS......EACH

I just sprayed wd40 on a rear axle hub. do I just wack the lugnut and pray?

I don't know if I'll get the oppertunity tommorow to take the axle some place solid to try and remove one.

Pray that you don't hit your thumb with the hammer?

How many Lire is that?

spline od .596, length .375

OD at hat .668, length .280

overall length 2.245, length without head 2.080

...and it's the lug nut STUD that you want to whack.

If you whack the lugnut while holding it you will wind up in the Emergency Room for sure.

THANK YOU CHRIS! Do you know what stud to use for the longer comp lugs? ARP doesn't seem to list them?

At$15 each, I ain't going to be wacking them with a hammer!

Thank you. I will let you all know if anything pans out but, frankly...it doesn't look promissing at all?

my googling for possible sources, I found other forum discussion about ARP making custom studs.

another tidbit I "learned" was a ARP comment "Do NOT clean threads with a die." Cleaning the stud with a die nut is part of my norm

They cut their threads with a roller device, not a die.

A die will cause microscopic fracture lines.

I haven't talked to any racers using long studs on a Pantera but I would presume that they have changed over to a Mustang 1/2"-20 variant?

Dorman makes a bunch of studs as well. I couldn't find the correct combination for them on my GT350 and wound up with ARP's on the front WITH the long Shelby lug nuts so that worked out.

GR-4 & GT-4 racers used competition versions of Campagnolos which had thicker mounting flanges, so the wheel studs are longer. How much longer and where one can find them today, dunno. It may be that GT-5 studs are longer, too but I've never checked. Maybe a couple of the big vendors could measure; Les Gray may have a source since he's still restoring his GT-4. If you use real GR-4 parts, $15 ea will likely be a bargain....

Look at the wheel studs & ALL the machining involved!!!

$15.00 apiece is a "Give-a-way"!

You would need to compare the prices to the ARP's to get an idea what is fair value?
Unfortunately they do not make Pantera studs at all.

$15 each is not cheap BUT I did pay $150 for 10 for the front of the Shelby.

Those fit well and I am glad that I did. A lost wheel on that car will cause a lot more than 150 in damages AS IS THE CASE WITH a Pantera for sure?

I think that I am border line now with the stock studs and nuts.

It would not be a bad idea to go to the longer comp studs and lug nuts.

You don't know when these things have saved you. Only that they didn't.

These are the long studs on the back of the Shelby which are made by Strange.

HEY Doug; That RUSTY, OLD pot metal jack stand could also cause Waaaaaaaaay More damage then the cost of a couple of new ones!...

It isn't rust that you see, it's experience.

When "1" of my rusty body parts doesn't work like it should...I'll tell my younger Japanese Girlfriend...

"Blame it on experience" or if lasting longer than 4 hours.

Have you contacted ARP directly?

They might even make it a stock item

The studs are pantera-specific as far as I know. Maybe some other italian car used a similar system.

Here are some of the studs I have. In the middle the std length, on the right the Gt5/gr4 studs, which are 10 mm longer and on the left some special very long ones made specifically for racing.

Where did you get the long ones from? Those seem to be for a thicker wheel flange?

Hi guys, I have had ARP make a run of special application studs before, when I had my vintage mustang big brake business. There is of course a minimum buy, but it was "reasonable". Don't recall the details...but may be worth chatting with them... I would imagine there could be enough interest amongst the community members to carry it.?.?

This may or may not be helpful but BARBARAM (bah-bah, bah-bah-Baram) has a set of 10 (new-used) on Flea-bay now for $39.

It's in the process. They sound like they MIGHT be interested?

I'll let you know what they tell me.

There is no secret rocket science to making wheel studs. It doesn't sound like anyone has approached them before on this subject at all which really is surprising to me?


Barbaram on ebay, is Mike Mayberry, aka King here on this forum. Some, I'm not saying who, need to expand their horizons...just a little?

Surely you don't mean me?

You think I don't know that?

Like in my post to SpeedU where I suggest that you have to buy the $399 wheel from "Barabara", but have to go to King to get the decal?

I know more than you think, my brother!

P. S. You forgot to put the Eye-roll or the condescending head-pat at the end of your quote!

You can't kid a kidder!

Who said I was talking about you?

Push, Very impressive sir. What do you do with such a long stud?

(sorry...the question had to be asked... )

Actually, all these studs (!) came with the parts I purchased from the Danish race-team which build and ran three Gr4 Panteras back in 2004-08. They were apparently spacing the Wheels quite a lot, so they had these made.

3" long studs is typical of US race cars, the reason being they use long lug nuts.

As long as I can remember it has been that way. I first noticed these on the late 60s "Trans Am" road race cars.

You will see them in vintage pictures of the Shelby Racing Co Boss 302's with the Minilite wheels.

Here is a picture of a lug nut from a Mustang that was raced.

This one was purchased from "American Racing Wheels" around 1972 and was used on my 200s wheels. It's 1/2"-20 thread.

The greater length gives you greater load capacity, it reduces the bending on the stud AND last but not least, they are easier to hold and start on the studs.

The ends are also open so you can see how far the stud is in the lug.

The standard length studs were notorious for snapping even just torking up the wheels.

I used Moroso part # 46185 but they are 1/2 20. The knurl is the correct diameter for the axle but I plan on running the rotor hats outside of the axle.

Well, yes, those are Mustang wheel studs. Virtually everything Mustang crosses over.

As a matter of fact you are reminding me of something with Dorman studs. I think one fits the Pantera if 'you' want to change to SAE 1/2"-20 studs?

I have to go into my 'Dorman' archives?

Hey...i wouldn't mind swapping over to sae. Who the heck would ever know.... If you come across those numbers please share.

You will loose the DT monogrammed lug nuts?

Some of the Vendors have DeTomaso monogrammed lug nuts in 1/2"-20. I bought a set from Dennis Quella a few years ago.

Remember Rocky..."The race is not over!"...

Hard to tell in this picture, but it's the best one I could find on the interwebs....

No. Wrong thread.

Good info... Thx

Kristian, can measure the thread length on the standard and GR4/GT5 wheels studs?

The part on the studs that not is threaded is it approximately same length on the standard and GR4/GT5?
