Brake swap

[MICRoS13]

** i searched before and couldn't get my definite answer. But on my LR knuckle there a bolt head that's been cut off.... so like i can't get it off and i need to change my rotors. someone told me to replace the whole assembly which i was thinking and would it make send to get a 1991 300zx rear spindle set with hubs and RUCA and the lower control arms all for under 200 bucks? & what should i do to my front as well should o go with z32 the same year or a ichiba 5 lug wouldn't matter

the rear works but not the front. has to be non turbo unless you gonna do q45 rear end
