Searching for bolt head mark identification

[Harry L.]

Is there a chart that I could identify the size and and head bolt identifications needed for my 1966 Vette?

Harry -

Do you have the latest edition of the '66 JG? It has lots of bolt/headmark information and photos.

JG = Judging Guide or sometimes TIM&JG = Technical Information Manual & Judging Guide

If you go to a football, baseball, or hockey game it helps a lot if you understand the rules of the game. If you go to an NCRS meet the judging rules are in the JG or TIM&JG. Don't bring a football to a baseball game.

To get a JM or TIM&JG click on the link at the top of the page that says "NCRS SHOP"

Harry,
Paragon has a poster that has a lot of them. Also Dobbins book has a lot identified too.

Gene,

Calli me as I have compiled along with the late John Woods and my 70-72 judging counterparts what we call the "Family of GM Hardware". This includes bolt head markings and the second page if I can find it has the hardware supplier's addresses. You have my personal contact info.

What I sent should cover everything at least as far as the chassi goes. Tomorrow, I will get you the rest of the finishes.
Best of Luck,

Our WNYNCRS news letter, see web site http://www.wnyncrs.org/WNY_NCRS/News.html
Go to heading "news".
The December '12 issue CROSS FLAGS on page 18 has a listing of head markings with original supplier info.
I dug up this from Thomas Registry years ago when I was working on the original 68-69 judging manuals with Terry.
