Halco C-3 wheel weights

[Lynn S.]

Anyone have any recommendations on where I might find HALCO stamped weights for my 75 with proper weight in ounces to the right of HALCO, and the 2 digit part number on the left of HALCO? Thanks in advance for your advice. Lynn

Lynn,

In my experience, HALKO (the JG misspells the name as HALCO) are virtually impossible to find. In my 10+ years of looking I’ve never seen NOS examples of HALKO weights.

You might search thru old TDB postings for Halko and Halco and you might see some photos of Halko weights posted by people who might have some used Halko weights to sell. You’ll have to search old postings for both “Halko” and “Halco” because people used the Halco misspelling because that’s what they mistakenly think is correct.

Hi Lynn,
When we were working on the new 3rd Edition of the 75-77 TIM&JG we could find NO original examples of Halko weights on any of our 75-77 cars we had in the group that still had original tires or spare. The most common weight was the "The Perfect Equipment Company" weight. I'm not sure why the Halko's were listed as the weight used in the 2nd edition. You might have more luck finding the " Perfect" weight. We did address this in the revision, however it hasn't been signed off on yet. "Micro" is another weight used during the 70's as well.
Here are a couple original " Perfect" photo examples I have from our study. If anyone out there has an original Halko weight on an original 75-77 wheel/ tire.... would love to see it.

Re: Halco C-3 wheel weights

Based upon this info, for upcoming Flight Judging, which weights should I install to minimize originality deductions since the TIMJG states HALKO weights? Thanks for everyone's help.

Satisfy a doubtful judge with a TDB post - interesting concept.

Re: Halco C-3 wheel weights

It’s not a concept, it’s an observation by dedicated NCRS members. Perhaps the Halko was an honest mistake or a rarity.

Make that a studied observation!

Re: Halco C-3 wheel weights

Gentlemen,

The 'concept' has absolutely nothing to do with the specific item referenced in this thread because it has been duly researched and documented to warrant an update to the judging manual. The concept that a doubtful judge will be convinced about any topic by a print out of a post on a discussion board is indeed interesting. If anyone has had such an experience first hand on a regional or national judging field, please post the details to share with other members. Any viable method of improving the judging process is always worthwhile.

Re: Halco C-3 wheel weights

I have a large assortment of wheel weights and the best thing I can tell you is to follow the Judging Manual if you are going to get your car Judged. I feel that more that one weight manufacture was use at GM for wheel weights during all years.

Re: Halco C-3 wheel weights

Poor Lynn Skipper is probably getting whip-lashed from the back and forth nonsense. Here's the page from the 3rd edition 1975-77 TIMJG...under review by the national judging leadership. BTW...it is the revision that's under review...not this page. Here's the essence and nice images in the attached.

Wheel Balance Weights
The inside of the wheel holds the wheel balance weights. A small daub of colored paint on the tire indicated the location and size of the balance weight. (See Fig. E 19.0)

Several manufacturers are reported to have been used but the most commonly seen on the wheels of 1975-77 cars are those of the Perfect Equipment Corporation. Its logo is a slanted P, pierced by an arrow.22

Footnote 22 reads:

The 2nd edition of the 1975-77 TIMJG listed Halko as the most commonly used wheel weight. Thus far, neither the 1975-77 team, nor 1973-74 has seen Halko wheel weights installed on wheels that sport original tires dated for the 1973-77 era.

I should add that several 73-77 Corvettes have been studied, low-mileage, original, many of which have yet to see a judging field, wishing to avoid its originality to be assessed against an outdated, twenty-year old manual. Members of those teams are among those contributing here...and thus the comment studied observation.

I agree. These wheel weights were being used by the MILLIONS across all GM car and truck lines and there were undoubtedly at least several manufacturers. I'm quite sure that for any given size weight the part number was the same regardless of manufacturer.

So, how does anyone know what branded wheel weights were used on their car? The only way to know would be to have an original, untouched wheel/tire assembly from their particular car. Not too many folks have that. There might be a few around with untouched original spare tire/wheel assemblies, though.
