64 front side embelms

[Michael D.]

Does anyone have any dimensions on the placement of the front side emblems, the old panels had been repaired and the holes were in the wrong place.
Thanks
Mike

See your 64 AIM, Section 11-13 sheet A1.00

See your 64 AIM, Section 11-13 sheet A1.00

I have checked that page and it does not tell me where exactly locate the emblem, it tell me the size of the emblem I need to know where to place it.
Thanks Mike

Re: 64 front side embelms

I'm not willing to remove the emblems to measure to the holes but if it helps:
From the front door gap to the rear tip of the "V" is 12-3/4"
From the ridge on the top of the fender to the tip of the flag is 5-3/4"

Michael, is your car a carb or FI?

Michael,

This is a lot easier if you have a template, as did the guys on the line. Lacking the proper tools, you have to do it the (very) hard way.

In order to use the information on 11-13, 1.00, you have to understand the coordinate system that GM used on these cars. I was once a GM body designer, so I'll try to help. (See section 1 pages A 33-39. Page 35 is the one you really need. The dimensions given on 11-13, 1.00 refer to the coordinates given there).

Here is how to use that information to drill the holes for the flags. If you have fuel injection theres a bit more difficulty, just let me know (here, I assume 64 dimensions are the same as 63, I don't have a 64 AIM, so you may want to check before you drill) A laser level will make the following much easier.

1. Important: do not assume the body is sitting parallel to the floor. It is most likely not. Jack up one end of the car until bottom of the fiberglass rocker panel is level. This is critical if you are to get the holes in the right location.

2. In order to locate the horizontal line where that holes will be drilled you need a reference point. HERE'S HOW TO FIND ONE: The rear edge of the front wheel-well lip has a straight, vertical section close to the bottom. Once you have found the proper vertical portion of the wheel well lip, measure 15 inches horizontally toward the front of the body from the inside edge of the that vertical portion. That locates the "-25 line", which is a vertical line passing through the center of the wheel-well. That vertical line will intersect the top edge of the wheel well at approximately it's center. At that point, find the bottom edge of the wheel-well lip. From the bottom edge, measure vertically 3.05 inches. Put some masking tape on the fender and lightly draw a level horizontal line at that height. Your holes will be on that line.

3. To locate the holes on the horizontal line you drew, go back to the rear edge of the wheel well that you found. A vertical line passing through the rear edge of the wheel well is called the "-10" line and can be use to measure the hole locations: On the right (passenger) side of the car, one hole will be located 9.52 inches rearward of the vertical "-10" line that passes through the rear edge of the wheel well. Measure 9.52 inches rearward of the "-10" line (-10=rear edge of the wheel well) and mark the hole on the masking tape. The second hole will be 2.04 inches forward of the first hole. Mark it too.

4. On the driver side, repeat this, noting that the dimensions are different: the first hole will be 9.66" rearward of the "-10" line (rear edge of the wheel well) and the other hole will be 2.04 forward of that.

Before drilling, I recommend you triple-check your measurements, then make a paper flag and tape it in that location to make sure it looks right. You might even use the dimension in the post below to check.

Good luck...

Re: 64 front side embelms

Michael G mentions "assume 64 dimensions are the same as 63" The 63AIM (Sec11-13 sheet1.00) calls for off set of .34 LH & .48 RH for the standard production car - then the FI badge is just added without any dimensions given (or changed) for the flag.
Well 64 is different. The standard production car is at 64AIM (Sec 11-3 sheet A1.00), the new dimensions are 1.34 LH & 1.48 RH as of a change around 10-3-63. No reference to ECR number so must assume it was the last one listed, 58529. The FI badge NOW shows the location of the flags that are back to the old 63AIM numbers.
So double check!!
The distance from the tip of the "V" to drill hole is 1 5/16". My flag hole is at 13 11/16" from edge of fender at door on a FI car (original stuff)

Its a carb 300 HP

Re: 64 front side embelms

Michael,
I find only the FI car had a different location for the flag & FI emblem, (interesting detail) So I would use those numbers shown in Sec 11-13 sheet A1.00, ie 1.34 LH & 1.48 RH which has the last date of 10-3-63. (assume car is after that).

To assure these new numbers are really correct, check out other AIMs to verify. So you though it was a simply question! Know each time I attempt to do some simple job on my car the questions take weeks until I think I've got the answer.

Re: 64 front side embelms

Alan, as I mentioned, my instructions were using 63 AIM data. If you could post the 64 AIM page, I'd be glad to revise my instruction per the numbers on that sheet. Thanks,

[Dan H.]

Re: 64 front side embelms

Michael, like Alan said, 64 carb flags are 1 inch further forward than 63 flags. Also, they are different on left and right hand sides. If you can find a 64 and make a template, you'll see the differences. The AIM is hard to figure out.

Early 64 FI RH side. The first photo is measured from the door gap, just above the style line. The next photo is from the top of the fender. The last photo is from the style line.

Thanks Paul, but Michaels car is a 64 carb, which locates an inch farther forward than the FI flags.

Yes Dan, I knew that. But since no one had provided pictures I posted these. He can add the inch to the measurements.

Re: 64 front side embelms

Here is the 64AIM location data.
Did this change continue for rest of C2's, anyone know?

And another little detail; is the distance from the emblem stud to the edge of the "V" (going towards back) the same for the early 3827158 (63/64) as the later & NOS part 3872930 ??

Note the distance between the studs but from stud to end of "V"
