Car is an 88 CRX and I believe the donor trailing arms are from a 91 Integra. Everything sems to be going well until I decide to install the CRXs trailing arm bushings in the Integra's trailing arms, because the donor car's were shot.

My digital calipers decided to break, but the best I can measure is the Crx original trailing arm bushings measure about 3 1/8" while the Intregra's measure about 3 7/16".

I went to two stores and both handed me the 3 1/8 bushings. I found that 95 and later Integra's have a different part #, but none of the stores locally have that part.

There was "3P" marking on the Integra's trailing arm.

At this point, I am wondering if I wasted money on a set of trailing arms or can I just transfer the parts over to the CRX trailing arms.

Here are pics of the trailing arms and bushings.

 

I may have solved the problem. After all the parts stores I went to, Rockautos catalog directs you to a Dorman part 905-751 with a larger diameter.
