staggered rivets

question about laying out rivet holes in flanges in 2 pieces that will be back to back. should i make the holes in the flanges parallel to each other
ex.holes in both flanges on inch marks or one flange on the inch marks and the other flange on the 1/2'' marks?
thanks for any input.
this is on a belly skin and i want the strongest if there is any difference.

The inboard and outboard wing skins come together with 2 rows of rivets that are not staggered. I think I would do the same.

Interestingly not on the -6 and I guess the -4 wings.

The plans show staggered rivet spacing of the two rows at the same inboard/outboard wing skin joint.

I'd stagger the rivets to increase the distance between them, although provided they have at least the minimum spacing per AC43.13, i doubt whether it would matter much one way or the other. However, in principle I'd go for greater spacing rather than less in the situation you describe.

Id do it the way its called out in the plans.
