Suspension, Brakes, Tires & Wheels - Rear disc conversion...(couldn't find answer in search)

I have a '97 EX sedan, disks in front, drums in back, ABS. I found a local guy who is parting out his '00 Si and wants to sell his rear discs (I believe full conversion, will have to double check) for $120. I know this is an awesome deal, what I don't know is if they will fit my car. Everyone says to go with integra rear's, but wont the Si rears fit just as easily if not better? Thanks a lot ahead of time, sorry for reviving this topic again...

im gathering as much info as i can but im still a little confused. what year of integra would be the best to do the swap. i have a 00 ex coupe.

Civic Si will definitely work. 94-01 integra will definitely work. I THINK the 90-93 integra might work but I'm not 100% sure

edit, I missed the ABS thing, now I'm not sure [8D]

im not sure either lol. so the best option is to go with the parts from a 94-01 teg?
