swap parts for 91 civic 4dr?
 

i have a 91 civic dx sedan, my rear brakes are about ready for replacement, but then i thought of swaping them with a disc brake conv., so i was wanting to find out from what year, model cars can i use parts off of. i want toswap inas much as i can, i love my civic... was also wondering if it would be wise to just buy a wrecked or cheap teggy gsr and part it out for my swaps?
