ZR2 suspension points

Hi All, my 2001 ZR2 Blazer needs a lot of body work... I'm contemplating doing a transfusion of the suspension and drivetrain components to a 2004/2005 2-door non-ZR2 model... I seem to recall someone mentioning that there are differences in the frame/suspension mounting points between the ZR2 and non-ZR2 models, but has anyone had the two side by side? Would everything just bolt up?
