Original 1967-1969 Camaro lug wrench question
« on: October 24, 2022, 10:58:57 PM »
Attached is a photo of a lug wrench from a 1969 Nova as well as 2 photos of my other identical lug wrenches which are all 99% identical to a pair of NOS 3909176 lug wrenches that I once owned. All 3 lug wrenches have the letter "O" on the lug head.  GM # 3909176 is listed in my 1967, 1968, and 1969 Chevrolet Parts Catalogs in Gr. 8.821 as the part number for the lug wrench for All 1967-1969 models. I believe that the 3909176 lug wrench was issued on the assembly line for 1967-1969 models as well as sold over the counter. These lug wrenches have a unique curves chisel end as shown in photo #3. The 1967-1969 Camaro Assembly Manuals do not list a part number for the lug wrench but rather a part number for the WRENCH CHART which is 3899546 (UPC 10 Sheet A2).
As per Chevrolet Parts History (for service parts) GM # 3909176 was replaced by GM # 3987070 in Dec. 1971.
Can anyone who owns a 1967-1969 Camaro with the original lug wrench confirm this?

Ed, I read the thread.
I have been collecting and studying Chevrolet 3/4" hex lug wrenches from 1960's and 1970's models since the 1990's for the purpose of finding the correct lug wrench for my 1970 Camaro SS350 long term project.  I have still have about 40 or 50 still in my collection with various markings ("O", "E", "U") and some without any markings. Their dimensions varies along with the angle bend. I sold my NOS 3909176 lug wrenches after I determined that they were not correct for the 1970. Attached are photos of some of my lug wrenches with the "O" marking. I always thought that the letter "O" was for Otterburn but do not remember where I got that information. Apparently the letter "O" is  for the Herbert E. Orr Company. I have been researching 63-67 Corvette and 67-73 Camaro parts for 4 decades and it seems that I still learn something new every day.

Yes - "O" stands for the Herbert Orr company. Have seen the letter "E" used.  There seem to be two styles of the lug part - a deep lug socket and a more shallower one for 1969.

Chevrolet always seems to try to have various parts made by 2 or more different manufacturers to prevent part shortages on the assembly line and to keep costs in check.
Attached are 3 photos of 3/4" hex lug wrenches that I have in my lug wrench collection with the letter "E" forged on the lug head. The one in the top photo was removed from a 1969 Camaro with the jack shaft dated "9A" (Jan. 1969) on the rivet head, the 1969 hook, and "U69" jack base  but I always assumed it was not original because of the shape. I might be right or I might be wrong about that. I never paid much attention to the lug wrenches with the letter "E".  The "E" lug wrenches are very similar to my NOS 14036400 lug wrench with the letter "O" as shown in photo #4 which was first sold over the counter about 1981 ($5.85 list in my Dec. 1981 Chevrolet Price Schedule).
Not many restorers pay much attention to having the original lug wrench for their vintage car.
I would appreciate any comments about these 3 "E" lug wrenches.

This is a guess but it might be a simple as you put it multiple vendors and the angle spec may have been +/- 15 degrees..  Hard to say unless someone runs across GM part drawings.
If you have solid lifter 1967 - 1969 Camaro please contact me as I would like to add your car's info to my database

I agree, a GM shop drawing would be very helpful.
