Part number is GOR73138J. They're typically available individually, and they're NOT cheap. I found a set of 20 at an online store I've never bought from before for $120, and they arrived quickly. I've had both positive and negative experiences with Gorilla lug nuts, but these seem like a very good quality. |

Nice find, they are a similar appearance to stock too.

I don't think anyone would call them out as unoriginal when they're installed, especially with the center cap in place

Since originals were 7/16-20 AFAIK no Pontiac that had snowflakes originally had metric threads (M12x1.5). What is the application ?
BTW Snowflakes use the cylinder tyle lug nuts. Acorn flange was for a steel spare wheel. |

KORE3 front hubs mounted to OEM-style spindle.

There are also some Toyota lugnuts that are metric with a hair longer shank.
I got some factory style converted to metric I have on the 12" 1LE rotor on the front of the 81 TA.

BTW don't ever rely on extension threads for strength.

Yikes! That's scary! But I wasn't referring to the threads in the shank, these don't actually reach down any deeper than the OEM lug nuts. I was referring to the threads inside the lug nuts, they're threaded all the way into the bore. Many lug nuts I've come across only have the first 12 to 16mm threaded and then the inside opens up with no threads at all. I run extended-length studs and I like having as much thread engagement as possible.

I replaced the metric lugs studs for standard ones in the 1LE rotors that I put on my 1976 Firebird. Dorman had a stud that was the same length and diameter with the correct shank in 7/16" size.

I actually had the Dutchman rear axles in th e81 drilled for 7/16(using those now) and metric if having different lugnuts ever bugs me. Metric 12 mm are pretty close to 1/2 so they do give you a little strength.

Once bought a trailer that someone with a bigger air wrench than IQ managed to drive M12 nutz on 1/2" studs. Broke three trying to get off and replaced all five. 12mm is .472".

What is the OD on those Jag lugnut shanks?

Factory lug nuts wiggle or not is more from the shoulder and outer recess on the lugnut vs shank as hole in wheel is .750-why they are hub centric!

Oh I know, I just meant that there's plenty of room for the Jag lug nuts to fit without interference

So here's a "fun" thing: the hub bore is wrong on the reproduction wheels. OEM hub bore is 70.3mm, which I confirmed on my OEM 15x7 snowflakes. The wheels center very nicely on the hub, there's no play. The hub bore on the reproductions is 72.6mm, which leaves a crapton of wiggle room around the hub and makes it absolutely impossible to center them since the nuts are flat-flange mag nuts with a shaft that's smaller than the stud holes. So the only way to fit these wheels is with hub centric rings, which are not included. That's really lame, considering they're supposed to be REPRODUCTIONS specific to this application... there's absolutely no instance of an F-body using a 72.6mm hub bore, they're all 70.3mm throughout all generations. I guess maybe they purposely made them larger than OEM so they could accommodate other vehicles, like many other aftermarket wheel manufacturers do. But in that case, hub centric rings should've been included.
Luckily, those hub centric rings are at least somewhat commonly available, so I can rectify the issue. But dude... still not cool. Hilariously, the Summit Racing listing for these wheels lists them as having conical seats for nuts, which is completely wrong. But I was expecting mag-style nuts, so that's not really an issue. |

My 15" have the same hub hole but my 17s do not. And like you said the lugnuts do not center it. I think for my 17s I had 2.87 ODx2.79 ID hubcentric rings made. Other option is lugnut "sleeves". Lugnut holes are .750. Most lugcentric wheels like my Prostars have about a 0.010 difference in OD vs ID. One of my Moser axles with 1/2 studs is a little tight in one hole.

Next thing that's wrong with these wheels: the center cap holes are too tight. I ended up damaging my previously-immaculate center caps putting them in there. It's like someone decided to remove clearance from the center cap bore and add it to the hub bore...
As aftermarket wheels, these are wonderful. They're relatively light, beautiful, straight and well-balanced (they had zero imbalance without tires mounted). All that for a very decent price. But as reproductions, they're kind of a failure. They require hub-centric rings to mount on their original application and they can't accommodate the original center caps without damaging them. I'm still not convinced about the accuracy of the color, but I can't confirm that. So far, I'm unimpressed. Also, I tried contacting OER to clarify something about tire installation, and I got an email back from a guy at Classic Industries who was basically a jerk. This tells me 2 things: - I should avoid buying anything from Classic Industries (I hadn't yet, but I was planning to) - these OER wheels are likely not the same ones Year One sells, as I originally suspected (although they may be cast and/or machined at the same Chinese factory). Near as I can tell, Year One doesn't sell anything from OER and Classic Industries doesn't sell anything from Year One I'm kinda wishing I'd gone with the Year One wheels at this point. Lesson learned... |

My 17" snowflakes from Classic have Year One cast in the backs!
