Before I get the usual, I have searched for this specific information already.

Car: 1990 Civic DX hatchback
Intention: To install disc brakes on the rear of the car to match the braking capability of the front (Fastbrakes 4-piston dynalite calipers, 11" cross-drilled, slotted rotors, stainless lines). My intention was to use all oem parts from the 91 crx si with the disc brakes minus the parking brake cables because they are too short. After the rear is converted I will be buying the 11" disc brake upgrade for the CRX Si from Fastbrakes. I know that they currently make a drum to disc conversion, however at the price it costs, I decided to go this route.

I currently have these parts, all new oem from Honda:
Both rear disc brake hubs (including bearings and wheel studs)
2 axle nuts
2 axle washers
Both rear trailing arm rubber protectors (rectangular piece that bolts to the trailing arm from the bottom with a metal plate and two nuts)
All new hardware
Lower control arms from the Si (powdercoated black)

Problem: I ordered new oem 91 CRX Si rear trailing arms. I already have a set of them from a parts car, however they are severely beat up from removing the lower control arm of which the outer pivot bolt bushing was siezed to the bolt. I ended up cutting off the welded on nut and bending the hell out of the mount for the lower control arm on the trailing arm. So I am really **** about the car having perfect oem parts on it with no rust at all. The problem I'm running into is that the trailing arms look to be universal as in that they do not have the bracket that bolts on with 4 torx bolts from the back that is used for the caliper bracket. I have these brackets on the old trailing arms, but they are rusted and beat up too and I would like to put new ones on the new trailing arms if I could. There is no part number for them on the catalog so I'm wondering if I'm just looking in the wrong place or if the only way to acquire this part is to get used trailing arms off a CRX Si. Is this part only available from a used car and not new from Honda? I'll put a picture up for clarity.

Part in question is circled in red.

This is the best I could come up with and it did not help much, The link is for a '91 CRX Si and the rest of the pics just show the other cars I tried, seems none of them list or even show that part. Man I wish I had a better answer for you for new parts but those are the only sources I have.
