Window is 4" narrower than RO, and Drip Cap ?
 
I ordered two windows from Home Depot. Both are Anderson 400 casement -viyal outside and pine inside.

One window is about 4" narrower than the RO. This is the next available size form Anderson to fit the opening. The opening is all drywall over studs.

The previous handyman nailed a 2 by 4 on each side of the window, inserted the window, just screwed in SOME the holes in the fin to hold the windows. The exterior for this window is plywood.

The instllation instruction from AndersonWindows.com is for new
construction and calls for house wrap the entire opening.

Questions:

1. This is not exactly new construction. What do I need to do to about this?
Do I house wrap to cover the 2x4 openings inside and out instead of house warp the entire window? then proceed to step 7 on Sill flashing, insert window, then apply flashing 2 sides, then flashing top?

2. Drip cap on Top trim board
The windows come with a very narrow (1 1/4"?) casing next to the fins
on all 4 sides. I would like to have a wider trim board 3 1/2' next to the casing. www.ehow.com/how_2075266_install-window-drip-cap.html suggets:
' Nail the cap to sheathing with galvanizied nails, making sure the cap slopes away from window. Caulk along top edge of drip cap. Cover nailheads with housewrap or felt cover, or use roofing tar on each nailhead'.
However, www.thisoldhouse.com/toh/asktoh/question/0,,518906,00.html
recommend
'Don't ever nail a drip cap to the wall; let the siding hold it in place. (Nails provide an avenue for water to reach the sheathingnot to nail the drip cap).

Should I nail the drip cap or follow thisoldhouse using siding or stucco to hold the drip cap?


Appreciate any help!!
