Europa-List: W20 Bracket spec

[Brian Phillips <barp99@gmail.com>]

I am currently attaching the port flap to the wing on my trigear, I 
find, for whatever reason, that the W20 bracket is too short by 12mm 
when the flap is in its correct position. Rather than live with this 
mismatch at the bolted joint, I will make up a new longer W20 bracket. 
Does anyone know what grade and temper these aluminium brackets are made 
from?
