Thanks for the info. A friend who has access to a hot line for parts advised to go with the 73' front end. His supplier said the S-10 would not work. I do have access to an early model S-10 complete truck with a bad engine. Even the interior is fairly good. The 1955 series-1 I purchased was used by a friend for parts and I am buying what is left. No engine, no seat, and pretty rough but certainly salvageable. It is a five window with a fairly good cab. Thanks for your help. I will be depending a lot on you folks from Stovebolt.
