I have an 89 crx that I did a rear disc conversion from a 91 crx. I also have a 90 integra parts car that im going to take the front brakes, mc, booster, etc from and put on the crx. I was wondering if there is any difference between the integra rear discs and the crx rear discs. I think they are fairly close in size so I dont want to waste my time in swapping them if they are pretty much the same.

The rear brakes are the same.
