    None of those look correct. I fond a fiat one on a site I believe would have worked but I lost all my bookmarks in an incident. I think I have one in Delrin somewhere that I made that I did not use if you want it shown below in black.
    You can see my bushing completely disintegrated. When you replace it with the tie rod ends and control arm bushes the cars is amazing.

    I think Miro is talking about the 4 mounting bushes to the bulkhead not the internal item which breaks up.

    I bought a bent rack for engineering exploration. It has good bushings that i'm saving for another day.

    I have to get in there and re-examine solutions for the rank end bushing.

    It would be great if you could take measurements of a mounting bush (biggest diameter, smaller diameter and length) and post here.

    I redid my rack in the spring the bushings are infact cone shaped. Worst comes to worse I can machine them from Delrin. I'd check bushing used on fiats too they used very similar TRW racks.

    Here is a picture of them when I was popping them out, (second picture) they are a taper fit. A steel washer sits int the recess hole where the press plunger is, I was pushing out the sleeve that goes through the set.

    Real similar to the Integra the 348 ones looked exactly those these shown directly below (not sure about dimensions) - Energy Suspension 16.10103G. I bet there is match out there somewhere...

    Some Toyota ones tapered also. I bet existing taper busing's can be trimmed too...

    Whiteline or Energy Suspension should be able to easily supply the mount bushings. Just need to get some dimensions and give them a call.

    Very interesting, the Toyota bushes (which Toyota and what they are for?). They look very similar to the genuine 348 ones:

    That Midwest Bayless bushing will not fit our racks.

    I think the later boxes used a different bushing. Ricambi does not show a part number for those.
    Here is Ricabmi picture for 89-92.

    Here is Ferrari Part 135139 I bought from Ferrari. When I get home I'll post detailed pics and dimensions. A picture I have on my phone below sorry it sucks I'll get better ones next weekend when i return from travel.

    REAL similar to the Toyota one.

    I wonder if the sway bar bushings fit? They were the same shape, see mine below from when I replaced all the bushings.

    Reached out to them earlier this year; they don’t have any solutions for that particular bushing. Didn’t discuss the mount bushings with them though.

    Very interested to see which direction this thread goes but I will tell you I replaced my bushes in my old 328 a few years ago. They look identical to the 348 ones just a different color and a whole lot cheaper than $106 a piece!

    I actually have 4 new bushes. Awitalin is down road from me. I can go compare the bushes in person in a few weeks if you want.
