You've identified an error in the plans. The history of this error is as follows.
The original 0.04" F-14133 parts were thinner. Van's found that it was prone to cracking
. So a thicker 0.063" part, F-14133-1 (hence the -1) was provided around Nov-15 to builders with the thinner parts. Subsequent kits shipped after this time were provisioned with the thicker parts.
The thinner F-14133 was thin enough to accept a dimple, hence the stale K1000-08D reference in the plans. The thicker F-14133-1 is too thick for a dimple.
Use K1000-08 for the countersunk F-14133-1.
Use K1000-08D for the dimpled F-14133.
