missing flap rivet callout?

[IowaRV9Dreamer]

Does anybody know the correct rivet to hold the flap main ribs (FL-905) to the flap spar (FL-903)? I've been looking at DWG 14 and I can only find the callouts for the nose ribs, or for the main ribs that also go through brackets, doublers, etc. I'm looking for the rivet callout for the seven center main ribs. I bet it is AD470AD4-4.

Maybe I've been looking too hard?

When all else fails: You want one and a half diameters of rivet to buck into a shop head.

Dave,

It's a little misleading, but the callouts are on section A-A and section B-B on drawing 14. Shows -4's for rib to spar, but there's -5's and -6's where the nose ribs are.

Not sure if they are the same as the "7", but I just finished my flaps and all the ribs were blind riveted using LP4-3 to the flap spar.
