Default F-750 baggage side cover to F-722 bulkhead

DWG 25 instructs to “predimple” the 722 bulkhead where the 750 rear baggage covers will attach. DWG 29 shows using LP4-3 pulled rivets in this location. All parts are prepunched for -3 (#40), but this obviously isn’t an issue to upsize.

So what say you? LP4-3 is not a countersunk rivet, so no need to predimple
Or
Use CS4-3 countersunk pulled rivet.

Is this a discrepancy in the plans, or am I missing something, Thoughts?

Default I'd noticed the same thing...

I took this to be an error, and though I haven't actually prepped these parts, I'm not far from working on these parts. My final decision on which way to go hasn't been made, i.e. whether to use CS4-3 or LP4-3 rivets. Might pay to check how tight of a fit the rear baggage bulkhead is, as it might need a fully flush surface to allow installation / removal.

My plan for now is to go with LP4, as most of the baggage area floors and sidewalls do not have flush fasteners, but good point on the rear bulkhead potentially being an issue.
