the NAA and 00 sereis hyd top cover valves are not compatible. I have seen an adapter block on a naa using some other type of valve.. but it's just as reare if not more rare than the naa valve itself.
many DA valves can be run as SA by turning an adjustment or changing a setting on the valve.
NAA valves come up for sale from time to time.. or you can mod your NAA blank cover and add a few bits and make a remote.
TOH helped me make one.. he did some custom machining on my top cover blank plate.. good straight drill and tap job. i assembled the hoses and valving and now my na runs a loader and has use of it's 3pt with no chains.. all off that slow 2.9gpm pump :)
