Looks good John. Don't forget to use sealant on the bolt holes & threads as IIRC all of them penetrate the water jacket. Don't want to get it all buttoned up to find out there are leaks.
Also, you might want to consider Jerry's (Hotrod Lincoln) reply post in this other thread about installing the adapter plate. His added step of a flush filler behind those upper pump/plate to block bolt holes will help with secure installation of the plate/pump and probably improve leak prevention I think.
