A long time ago, I did the fairly common approach of notching the outside edge of the 705G angle (that nests up under the seat back brace) to provide some room for the skin/longeron rivets. Welp, it turns out my notches are still too small to make solid rivets work. I know it's not unheard of to just use pop rivets for the last 3 rivets that the angle interferes with. Do I need to use Cherry Max rivets for this, or is something like a CS4-4 adequate given the location (I thought about MK-319BS, but they don't have a long enough grip)?
