Rivet line drawings

Is there a good source of like drawings somewhere? I am building Hasegawa’s Nakajima B6N. The kit is pretty nice for a 1998 kit, but there is a distinct lack of riveting. I have a rivet tool and think I would like to add the rivets but would need reference to the rivet spacing and positions.

I don’t necessarily want to buy a full book for this as it will be a one off build

I always go to the Internet for this. Google search for Nakajima B6N Kate drawings with rivets. Try different combinations of search terms. Search in images as well as the web. Once you find what you want, Paul Budzik has a video on scaling a drawing on YouTube (Scale Model Workshop).
