Vintage and Classic Games

I build models, and I want to do a diorama scene of the Green Acres main characters' homes. I will do it in model railroad, HO Scale (1/87:1) scale. I found a book called "TV Sets, Fantasy Plans of TV Show Houses, but the drawings are simple, and have no dimensions. I have a tractor models which will be perfect for Oliver's "Hoyt Clagwell" (fictional) tractor. I still need an HO scale 1966 Lincoln Continental, and a "C" cab, stake bed truck, of unkown vintage or maker. A mid 60's Ford Bronco in HO scale would also be nice, but not essential. I have many episodes of the show on tape, so I could estimate dimensions from stills of various scenes. But, actual, dimensioned drawings would be neater. I will build the house, barn, general store, and several others from raw materials (scratch-building). I will use a mix of commercial products, and custom made items for the scenery, the people, furniture, and other details. I am a semi-pro model builder, but I could sure use help.
