i want an HF, but i only see 88's around here..

 

it should bolt right up. i put 91 rear suspension and brakes on my 89. it was really easy to do.

 

I take it then you did the whole trailing arm/knuckle/etc? Reason I ask is I'm looking to get rear discs in the near future...

 

the reson i did it was to get the rear disc brakes on my car. i figured it would be easy to get the whole rear suspension and brakes of a crx si and just bolt it on. it only took about an hour or hour and a half to do. it made a big difference too.
