Hi Everyone, I am hoping someone can answer my questions here because I have tried everywhere else.. Even the Chevy dealer and they were not sure..? I recently acquired a 1972 GMC Jimmy - aka Blazer and discovered that the frame is well, pretty rusted... I came across a frame from a 1984 Blazer and was hoping that I could find verifiable evidence that it could be swapped over before spending time & money getting it.. The 72's body is in ok condition as that portion was covered most of the time but everything else is pretty bad... Has anyone done something like this and if so, were there any kinks in the plan... My research has found that the frames are the same from 73-to 91 but that's all I could find on the internet - no mention of the 69-72 models..? If anyone can help, please let me know ASAP as I have to make a decision before the donor finds a new home.. Thanks, A.J.
