Just so you know - you may not have a "riveting drawing(s)" (if you did I hope you have a large room to store them) as in many cases aircraft major assemblies are built in assembly jigs and rivet patters may not be shown on large assembly drawings, this varying with manufacturer. Sub assemblies and smaller components may show rivet locations. I haven't really studied WW2 Douglas drawings so I'm not 100% sure how rivet patterns may depicted. Good luck.

Just took a little time running thru the drawings over on AirCorpslibrary.com to verify the data. As with industry standards, all rivet locations are either called out specifically, or in non-critical installations, end point rivets are called out exactly, with a notation of so many rivets equally spaced between designated locations. There are a little over 12,200 drawings, but not all will be relevant.
In tracking the data that you are looking for, realize that you may have to climb or descend the Next Assembly or the Parts Required tables to actually find the information. Within the drawings, you will also need to read the assembly notes for fastener codes and pay close attention to Section views for material or hardware stackups.
If you've never read assembly or detail drawings, it takes a couple hours of intense study of a range of drawings to begin to understand the individual company's standard practices and part number coding. After a couple of heavy weeks of working with the drawings you will gain quite a bit of speed finding what you want and understanding how things go together.
When I was a lead guy on the production floor, I could get my new kids, even though some had 10-15 years building airplanes, up to speed on our drawings within about a week or so. A few would struggle, but within a month, all could read the drawings and chase all the data they needed for their tasks.

I have previously posted a couple of manuals on reading WW2 blueprints as have others. These should help you. cvairworks might have some later manuals that may help also.
The industry standard fastener code NAS 523 (from memory) was not produced until post war so wartime drawings have lots of company specific items in them, hence the should and may above.
There are several Drawing office manuals on the site that will also help, but from memory nothing from Douglas and I have nothing from Douglas in my collection.

Newest one I have is a Navy course book from 2003. Not sure where I downloaded it from. Here's what I have:
Airplane Metal Work, Vol 1 Aircraft Blueprint Reading by Alex M. Robson, 1940
Aircraft Blueprint Reading by Almen and Mead, 1940
Aircraft Sheet Metal Blueprint Reading by Harry H. Coxen, 1944
US Navy Blueprint Reading and Sketching, NAVEDTRA 14040, 2003
Packed away, I also have a couple of books on aircraft lofting, but those are getting way off in the weeds, unless you want to learn how to actually loft lines on Mylar or Velum. CAD is much better for overall work, but there are times that you can't put a part against the tube and check it for conformity like you can with a Mylar. 1st article checks and master tooling checks are all done with either lasers or CMM's now days and the computer will spit out a deviation sheet on the part.

All I have is posted at Aircraft blueprint reading along with other documents from other members. Included are Almen, Coxen, Robson and a 1994 edition of the USN book.
I have never had the pleasure of working with mylar or velum - just paper - so envy you. It used to be possible to do full size accurate prints from microfilm using a fancy exposure system using the same spec lens as the original camera. I still have a bundle of metre square prints from one project. The cost was horrific but the labour savings in transferring data from a non scale print to metal were worth it - and it took only one mistake on a big piece of metal to more than recover the costs.
