Countersunk
Sometimes I do not know when to stop.
For example, when I was countersinking the rear spar doublers, I forgot to stop.

In the top set of rear spare doublers every hole is counter sunk.
That even includes the doubler fork (W-907B) though the holes below doubler (W-907C) are not countersunk.
The bottom set of doublers is correctly drilled. I tried to order new doublers but they were not on Vans on line list.
Now, should I try to order new parts, or counter sink the rest of the holes?
I contacted Vans for their opinion.
Vans said to use countersunk rivets, but I could order new parts from them.
So I ordered new parts.
