MJ,
This is not a good example of a car with factory applied, unequal width stripes. The stripes tended to be unequal width at the front of the hood, but as they turned the corner toward the side of the hood, the inner stripes also thinned down to approximately 1/8" and were pretty much equal from there until they neared their termination point at the rear of the hood.
The stripe pattern for most 1970 LT-1 Corvettes also tended to be more "round" at the front of the hood compared to the late 1970-1972 which tended to be more angular.

My first post is in agreement with yours... Very late 1970 LT-1 Corvettes as well as all 1971-1972 LT-1 Corvettes would have used the equal width stripes. By 1972, I don't see how it could be any different.

The sheet from the AIM is interesting, but my guess is that engineering never got around to changing the documentation in the AIM... I can't say for certain why it is there, but the fact is that in 1972, the factory was applying equal width stripes exclusively, regardless of what was in the AIM.
If you prefer the appearance of the unequal width stripes, have at it! If you're looking for what the factory was doing in 1972, then you want to go with the equal width stripes.

GaryS: Stan: I can relate to my copy of AIM 1972 and enginerring not correcting or updating 72 Aim....but, on the same token... This 72 hood was revised 1/20/72 from the 3962690 hood as indicated on my drawing above 
I'm curious, would the 3962690 Hood the equal stripe hood? Thanks: 
Don
WB: Thanks for the link, as indicated above... I actually have a stencil
72 LT-1: I'm pretty sure (not completely) that you can not re-use the stencil. I have a new stencil here which I did not use... I was going to send it back but would, I belive, lose a 30% restocking fee. You certainly can have if for that if your interested... I'll find out for sure on Monday...

This is a closeup of a 2,866 mile 1972 LT1:
1972 LT1 Pin Stripe
The view is taken at the bottom of the scoop where the pin stripe begins to wrap up toward the windshield. Note while the stripes are even...the disjoint where the two units were joined. Factory applied!

The labels that you reference appear to be the black/silver style which was used on "early" 1970 LT-1 Corvettes. The label changed to a black/white style later in the 1970 model year and was used until the end of 1972.
The black/silver labels are tough to find and this auction would be worthwhile for someone restoring an early 1970 LT-1 (or possibly "trade bait" for a set of later style black/white labels). Don might be better off waiting for the black/white labels if he is looking for accuracy.

Don,
As mentioned before, if you're simply looking to stripe the hood to your taste, then the AIM page that you intend to use for reference should help in that regard.
If you are looking to replace the stripes in a manner that they would have been applied in 1972, then the AIM data that you have is inaccurate as that is not how they were originally applied.
Hunt4cleanair: Wow, that is amazing 
I can't believe GM would let that out of the plant!!!

Stan: Yes, I agree and afirmed by Mike (pin stripper). As I indicted above, Mike is a very technical guy and will stripe exactly as the AIM drawing shows above which, as you pointed out...not correct (NCRS) for 72. Needless to say, I have added a few items to this LT-1, Dynamat, heatshield, rims (bolt on items) nothing permanant The only things I'm missing is the emissons equipt and vertical plug shields and of course the equal stripes 
to be correct.

The striping operation for 1970-1972 LT-1s was done by hand in a production line environment... Which means the application quality of the stripes could range from very good to marginal. Believe it or not, the photo of the low mileage '72 that Tom posted (Sal Carbone's old car Tom?) isn't too bad, although I have seen much better on original cars.

but on the same token can relate. I suppose it depends on who was on shift and what they had to drink...wether it was a Friday or a Monday Vette ect. Thanks for the input Stan...its been a striped learning exp.

On a similar note, The NCRS judging guide states all 1970 4-speed manual shifter ***** were all black chrome.....which I know to be 
.....My 70 LT-1 has chrome and has been verified thru pevious owners back to the original owner who purchased it from a dealer in Des Monies Iowa.
From what my brother, who worked at the Corvette plant for a while, tells me......it wasn't uncommon to use substitute parts to keep the line moving They probably ran short of black chrome and substituted left over regular chrome????

I agree with both of you my 1971 had equal strips and my friends 70 had the unequal. NCRS is correct.

Regarding the unequal width stripes found on most 1970 LT-1 Corvettes.
Compare this photo...
...To these photos of an original paint 1970 LT-1.
You'll notice on the original paint car that while the stripes are unequal width at the front of the hood bulge, they narrow to equal width as they reach the radius where they turn toward the rear of the hood. This has been true of all original paint cars I have seen with the unequal width stripes.
