Original 67 Rally Lug Nuts?

[Kirk M.]

Can anyone tell me if these are original 67 rally wheel lug nuts? Some of them are marked "DMC".

If they are, is there any reason that I shouldn't use these to mount my rallys?

Thanks.

My 67 vin#7471 has the waffle pattern on the face of the lug nuts. I would bet that there was more than 1 supplier of lug nuts.

Hi Kirk:

The lug nuts are not visible during judging, so this is not a judging issue. It is my understanding that original nuts had the waffle pattern.

I can't tell you if these are original nuts for a 1967. GM was using these nuts by the MILLIONS across most GM car lines at the time. While one supplier may have predominated for the St. Louis plant, I'll bet that at least several supplied, to one degree or another, wheel lug nuts in any given model year.

I can tell you, though, that these nuts appear suitable for re-use from what I can see of them. Nuts which have significant galling on the cone area OR thread damage are NOT suitable for re-use. These nuts do not appear to have significant galling on the cone area.

The ones that are stamped have the waffle pattern you are talking about. 7 waffles and 13 stamped "DMC".

Thanks. They look to be in good shape to me. Just wanted to make sure there weren't any period issues with this type of lug.

But I will know they are there. I just want to run/drive my vette with as original appearance and mechanics as possible. The fact that by doing that I might actually qualify to get some awards from the NCRS only gives me even more positive feedback to help propagate my current mental condition, which is routinely questioned by my wife!!!

It's possible that differently supplied lug nuts were originally installed on the car. Assemblers at St. Louis would definitely not take care to use a "matched set" on any particular car if their parts bins happened to contain both style nuts (which could happen). However, it would be, by far, the exception rather than the rule. If you have some waffle style and some of the other style, I would suspect that the other style are replacements "along the way".

Here is a picture of 2 known 67 lug nuts. I have seen your DMC lug nut before but don't remember if they are 67 era correct.

Your waffle pattern lugs look identical to mine.

Here's the part drawing for the GM lug nut originally drawn in 1929 and since updated. Like John stated at the rate GM was using this part there was most likely a number of different suppliers.

That pic is great. Thanks.

I love print history/ change logs.

Did anyone notice the revision date that then made it a requirement to add the supplier indentifier was added in 1969? That implies it was optional before then?

Ron -

The change #18 note probably replaced the usual "Supplier identification must appear on this part" note that was common on drawings in that era.

Re: Original 67 Rally Lug Nuts?

John, Maybe, probably, hard to say as #18 is a "notation added", the mystery is the redrawn without physical change and what constitutes physical change would leave this open to have #18 added.
