Midland makes a universal NMO mount for the hood that is looks very similar to the (same?) as the TRAM mount pictured above. Not a huge cost difference so I ordered one from Amazon among with a TRAM rain cap. I was able to install in on a couple of locations on the hood and ended up going with a similar mounting point to what others have done with the TRAM (passenger side upper left).
