I found the wood blocks and sheet metal screws don't hold up the cowl well. If you look carefully you will see that the position of side screws and top do not match. I have blind nuts going to side of fuse instead of glueing wooden blocks for sides and top could not be done due to foam so I glued one block and blind nut. Using locktite and rubber backed washer will hold up cowl without loosening for long time.

I opened up monocote directly below the stab to apply glue directly around stab and fuse and resealed.
