[Antennaware] Cushcraft A26-9 6M/2M Yagi Modeling/Dimensions

[Michael Haack, WB9B]

I know somebodies got the answer to this one...

Here's the problem.
I picked a almost "like new" Cushcraft A26-9 6M/2M Yagi the other day.
The antenna was literally only used once or twice for field day.

Cleaned it up, it had been sitting for some time... ( it was made maybe 
early 80's)
And when it comes time to re-assemble it, lo and behold the manual has 
no spacing dimensions.
Just the "put it at the mark on the boom". Marks that are long gone.

So question is: What is the spacing/placement for the 6M elements?
Hopefully somebody has one and measured it at one time, or can model 
this one.
The current Cushcraft A2670-13S would seem to be close in layout.

Antenna: Cushcraft A26-9   6M/2M Yagi
Boom length: 12' total 1-1/4".
With the 2M beam forward on the boom effective boom length for the 6M 
looks to be about 7 feet.
Elements are .750" non-tapered.
Gamma matched.

MFJ, has no record or knowledge of the antenna. The advice from them was 
to either simply try even spacings. Or Model the antenna.

Thoughts? Answers? Anybody?
