Looking for plans of my 5 br Eichler

I've searched some other sites (http://www.eichlersocal.com/floorplans/FPindex1.htm) but I can't find plans for my 5 br Eichler in Menlo Park.

Ours has a 2 car garage and the Master/Den are opposite the other 3 bedrooms and kitchen.

Any suggestions? Apparently it was built during the early 70's.
