CX-7 rear suspension similar to Mazda5?

New to this forum so hi everyone, I've recently read about that rear suspenion in cx-7 is "borrowed" from mazda 5. Is it true? I need to change my bushings. So does anyone have infomation about if rear bushings in mazda cx-7 and 5 are the same?

Maybe someone know what is diameter of those bushes?

Thanks for any help.
