I have seen/read conflicting information on these forums. Regarding the trailing arm bushings, that Honda recently started selling separately from the trailing arm for 5th gen Civics, which should also fit 3rd gen Integras:

I have seen 2 different part numbers around here.

52385-S21-003 RR TRAILING ARM BUSH $29.71
52385-SR3-000 BUSH, RR. $46.36
*edit*
52385-SK7-N02 BUSH, RR. $50.52
*/edit*

Both found at San Leandro Honda Parts www.slhondaparts.com Majestic Honda actually has them for a bit cheaper, but many other Honda Parts sites do not, and neither does Carland Acura or Delray Acura.

That 2nd number I found more recently as being listed as a trailing arm bushing for the 94-01 Integra. But I'm not so sure about that, going by the description shown from SLHP. Unfortunately it won't show me a diagram where that part applies. From the description it's just calling it a "rear bushing". Rear bushing for what?

Can anyone shed some light?

*edit* actually I've seen THREE part numbers floating around. I added the 3rd one above.

 

Nevermind I found the answer.

52385-S21-003 RR TRAILING ARM BUSH $29.71 this is the correct part number
52385-SR3-000 BUSH, RR. $46.36 this is the old failed part number
52385-SK7-N02 BUSH, RR. $50.52 this is for 90-93 Integras and will not fit 94-01 Integras or 88-00 Civics
