Hello again:
Just was given an original parts book (quite greasy) for 1941-1955 Chev and GMC Truck Parts.
Haven't looked at it too much yet but it has pictures of all models we were talking about here. The terms This book was published by GM in Canada.
Hello GMC48Sub
This book does not use the term "clamshell" that I have found yet but uses these terms:
"Surburban Carryall with End Gate" or
"Suburban Carryall with Panel Type Rear Doors"
I seem to remember seeing a Chrysler woody car (not wagon) in a magazine with what they called "clamshell doors" There was a lift up and two piece lower door like GMC Chev Astro
Safari "Dutch Doors" but certainly "clamshell shape"
Maybe that is were the term came from.
Around here the panel type doors on the newer Suburbans are called "barn doors"
Thanks again to everyone for the information.
Ter
