That sounds right. Removed the shelf and old AC Insulated with 3/8" foam reflective siding, installed w 1/4" lag bolts and plumbers tape to secure. Built a sheet metal duct to 2/3 of vent then insulated duct, used the fan blowing in.. Sealed the whole area with AC aluminum tape, foam under the shelf.. Cold air!!
Pm me if questions..
