Something doesn't quite look right about your tripod installation. The main tripod leg of the foremast was anchored to the main deck. In the case of ex-USS McGOWAN, the leg passed through the Commanders Cabin before going on to the main deck at the cross walkway between the forward deckhouse and the midships deckhouse. In your model the tripod forward leg should show to be attached to the Commanders Cabin "roof" aka deck over the cabin. You have the option of just anchoring to the top of the Commanders Cabin or to pass the forward leg all the way through the cabin to the main deck.
Attached are drawings of a typical FLETCHER (in this case DD-795) inboard profile showing the foremast forward tripod leg (as an aside; notice that there was a angled brace from the fire room bulkhead to the base of the foremast leg and an outboard drawing of USS McGOWAN herself showing the relationship of the tripod to the Commanders Cabin. Also, I added a pair of views of USS AMMEN that shows nicely the layout of the Commanders Cabin and the interface with the foremast tripod. Also, it clearly shows (better than the other views) that the cross walkway was still there.
The Revell 1/350 scale FLETCHER kit really screwed this up, putting the mast in the wrong place.
