cordoba brakes

hey guys. i was at the junk yard today and there was a 75 cordoba. can i use this year for the larger front rotors and caliper brackets? i was also wondering about the rear backing plates for the larger drums. oh and also. ive been looking for a 8 1/4. there was an aspen down there with a larger rear end in it. would that be an 8 1/4 and if so. would it work in my scamp? thanks.
