ok i have 88 si and the preowner swaped a disc brake already. I dont know if the rear brake converted from older SI or from 90-93 Integra but i need to replace the driver side, cuz i bent it from an accident (spun out hit the curb) and now the toe angle is not right.
The question is rear trail arms and knuckle from crx si and 90-93 Integra, are they the same? cuz i would like to just replace the driver side only. If they not the same then i have to replace both of them so they wont be mix match

 

i don't know if the crx si and the 90-93 tegs arms are the same...i suggest getting the 90-91 si. it should just bolt on since the swap has already been done.
