[c20olive]

Hey fellas I've got a c20 I'm looking to change over to 4x4. I have found a suburban but it's a 73-87 model. My question is how much different is the suburban frame? I have also found a 3 door suburban it's a 67-72 truck I'm not sure the exact model on it either but would the frame be a better fit? Or is the suburban frame all together different!
