Default Dynon Pitot Mast rivet sizes

Anyone know / remember the rivet callout for the Dynon Pitot mast installation to the lower skin and spar? Nothing in the manual... Thanks in advance for the help

Should be easy enough to calculate or measure. Place a 470 rivet from the inside facing out, so the tail is outside the skin and measure how much stick out you have. Then chose the correct 426 rivet and get to riveting!

Just use the time-honored formula for the amount the rivet shank protrudes:

1.5 x shank diameter

I think this is the size I used along the spar, but I just did what others said & checked the rivet length before setting them.
