wanted to give you guys an update... picked up an inline valve from Napa, it's a Balkamp #660-1413 for $23. It's a screw-down type and not cable operated. Last night drove 20 miles roundtrip to a local cruise night in Herrin, IL and cab was much cooler, well as cool as it can get with all the holes/openings I still have to cover at 90+ degrees. Next project will be sound deading/heat blocking...
