Hi everyone, I own a 71 240z that is completely rusted out and a 72 shell in what I thought to be good shape, but unforntunetly I just figured out that its crooked... I've spent the last year or so picking and rebuilding all the 240z suspension and drivetrain parts... bought the toxico springs and struts, bushings even the rear disc conversion, not to mention the motor mods... ( id like to throw a shout to all you members, although I've never posted before, I've gathered alot of information from this site aswell as many others...thanks so much) However, I dont have a decent frame...ones rusted to $^!# and the other crooked and I dont beleive I could ever really straighten it... so Im looking for a new shell.. I have found a perfect 78 280Z shell, other then the normal stuff like bumbers and extra rails in the doors is there any differences between the actual unibodies... I've heard that the actual sheetmetal used is little thicker, but this cant amount too much more then a 100pounds... I also know about the excess in wiring, dash and engine weight..this dosn't concern me, as I would use all the parts I have already rebuildt and painted. Is there a difference in the placement off suspension assembly.. I bought the 240z toxico lowering package, I assume the only difference beteween the 240 and the 280 kit is the weight rating.... thanks in advance for any help.... Emile
