I have the old aluminum slotted mags on my 73.  One wheel has different shaped lug nuts from the other three.  I tried the Dorman replacements from the local auto parts store, but they don't fit.  So I'm looking for 4 used lug nuts.  I tried ZCarSource, but no luck.   Picture below shows:

 

• Top - New one that looks correct but doesn't fit.  The shank diameter is too large, but the head shape is correct and matches my others.
• Bottom - Current set that fit, but head shape doesn't match my other 3 wheels.  Dimensions:
  • ​Shank diameter:  .680"
  • Shank length without washer:  about .80".  
  • Washer OD:   about 1.06"
  • Washer thickness:  about .13"

Any help would be appreciated!

 

Thanks, Ken

 

There's some on e-bay, zcardepot.

I had a hard time finding nuts for my mags also.  Finally found them at either a Baxter or an Oreilly's.  Gorrila nuts.  Looks like you might be able to get them on Amazon.

 

I'm not positive on size, or thread, but Amazon says 73127 fits.  Due diligence.

Thanks for the link.   It looks like those have a .75" diameter shank.     I must have a weird set of wheels.

I likely have them and if you cover shipping they are yours

.685?

 

I'm having invisibility problems.

Look like those 73127's will fit, but don't have the rounded head to match my others. I guess I could buy all 16.

PM sent, thanks.

Your original lug bolts look like the ones that came with my 71. It had a set of slotted alum. US Wheels. I remember that they were a minor PITA due to the tight fit in the wheel & the extra length.

Here are the ones like on my other 3 wheels.   They all have the 2 small grooves on the hex corners.

Not sure what make they, or if they are the originals, probably not.  I've got one make of slotted mags on the left, and another make on the right.   Hard to tell unless you look closely, same size and offset.  This side has the flat lug surface indented from the slotted area.  The other side is raised.

And they are the "PITA" style mentioned above.

 

 

I have quite a few of the style you need... If you dont get them elsewhere,just PM me,and you can have them for postage.
