have fun wondering.
a easier way to tell if they fit is to put the zz next to the diecast and to make sure that the wheel base is the same. if that works then it should fit, as long as the body is long enough. rip the body off, and put it on. use a electric drill to then make two slits in the car where the tabs are so it can fit on, i recamend to make the body a little lower. if the body is too big, then you can stick some plastic on the inside to extend it to the middle of the car, and put it to rest on top of the tabs. hope that this helps!
