Default Plans error - Attaching vertical stabilizer RV8

There must be a mistake on plans sheet 73 in the 1/2 scale view showing the 3 bolts that attach the bottom of the vertical stabilizer to the bulkhead. The plans drawing shows the vertical dimension between the bottom bolt and the top two bolts to be 7/8". However, this cannot be correct. I'm guessing the engineer failed to apply the scale factor (1/2 scale), so the aictual dimension should be closer to 1 3/4". Can anybody confirm?

There are apparently 2 versions of DWG 73

I see a dimensional callout of 1 23/32 where are you coming up with 7/8" ?

There was a drawing revision.

Thanks to both for responding. My plans date is 11/15/05. View 'AA' at the top of page 73 is 1/2 scale and clearly shows "7/8 2PL" for the distance between the bottom bolt and top 2 bolts. The 1 23/32 distance makes sense. I'm sure this dimension was inadvertently applied to the scaled-down view instead of full size, or incorrect scale factor used prior to printing. As someone who used to use Autocad quite a bit, guess why I suspect this?
Thanks again

Slightly off track, but:

Hopefully a professional engineer/designer using AutoCAD is controlling plotted scale by correct use of viewports and layout scaling instead of simply drawing the view 1/2 size in model space! Scaling plotted views by correct use of viewports does not change the displayed dimensions.

Default Vans Plans

Van's typically recommends that those who have old drawings purchase the digital drawings with the latest and greatest revisions from them. They'll send them to you on a memory stick, resplendent with the Van's logo. It's not expensive, and it's pretty handy to have around.
