I am on page 36-4 of RV-10 build. Putting in brake lines.
Last step is to rivet the heat duct onto tunnel walls. It says to use CS4-4 (counter sunk head) pop-rivet. Yet, no previous step shows to dimple or C/S the holes. If I use a LP4-3 (standard pop rivet) am I creating a problem down the road? I'm using Aerosport console and interior panels, and see now reason why a c/s rivet must be used.
