im getting ready to buy a 83 i think chevy 4x4 4 speed long bed..the drive train is a 79 but someone has put a 83 model front clip on it..how hard would it be and what all would i have to do to change it back to 70s front end..i know the body panels should bolt up i just not sure about the wipers since the 80s was on the cowl and 70s was under hood..all help and answers would be appreciated
