I may be a bit late to the party, but anyone interested in AMC products from the mid-late 60's should check out "Too Many Projects" on Facebook. This resin caster has an amazing selection of AMC's from Ambassadors to Marlins, 2 doors/4 doors/and wagons. I just received a '67 Ambassador that I bought from his May yard sale. FABULOUS casting quality (except for some excess flash which I knew about already) Great stuff! He also has a great selection of older Mopars, Crown Vics and other forgotten older cars.
