Are these the same on 1988-1991 SI's. I know the 88-89 had drum on rear but don't know if this changes the trailing arm.

 

88-91 civic trailing arms are the same as 88-89 crx's, 90-91 crx si's came with discs and will also fit.

 

awesome, wouldnt this be the ideal time for a disc brake conversion? what all will my buddy need to do that

 

trailing arms, ebrake cables, brake hoses, proportioning(sp) valve, master all from a rear disc car.

 

I would, it is much easier to replace brake pads than brake shoes.

 

Just so im completely sure, if I go get the trailing arms off a 90 CRX Si, they will fight on an 89 CRX Si with no problem correct?

 

correct

Indeed. Don't forget to get an alignment done when your finished.
