I could not agree more the MII is not the end all be all that some would have you believe. I do not like them because they load the unit-body in ways it was NEVER designed. IMHO the only way to do it correctly is as stated early and that is to build a cage around it and even then you need to make sure that ALL of the welds are very good. You just cannot compare a framed car to a unit-body car they are totally different animals with different care and feeding requirements. This is in no way meant as an insult just one mans opinion but I have conducted the research and I do have some experience.bnickel said:the main reason that street rod guys use the M-II setup is because it is a million times better than the old solid axle suspensions those cars came with and those cars also have full frames as well. if you are dead set on the M-II then fine but at least take the time to strengthen the chassis and build some supports, think roll bar type cage, for the front suspension, especially if you plan on running a big block.
