    In preparation for my Getrag 5 speed install I have been preparing the short throw shift linkage and was not satisfied with the crappy plastic bushings that came in the new rod joint or the used 320i lever. BMW does not sell replacements for these. So I measured the size of the bores and it is 10mm ID x 13mm OD x 20mm long. A quick search yielded a most excellent company that sells the exact fit bronze bushing.

    The plastic one was removed from the shift lever, there are grooves in there but the bush is tight so no adhesive needed. I Dremel'd the inside with a wire brush to clean and smooth it out:

    Then I tapped it into the lever, it overhangs about a mm on each side (where the original flange would be) and is not quite as tight in the 144mm dog bone DSSC linkage piece as I want (nor was the plastic one) so I am fitting two 10mm x 16mm x .25mm shim washers to make it nice and snug. Then I torched the plastic bush out of the new rod joint, there are large grooves inside it so I put some JB Weld in and tapped another bushing into that, it is very snug and won't need washers between it and the dogbone:

    That's the old plastic lever bearing in the above pic. Now I have tight, smooth bronze bushings that won't distort over time like plastic or have as much play.

    Steve, thanks for this excellent thread and photos.

    I am about to embark on the same journey. I have a 320i shifter and was reviewing your bushing suggestions.

    I noticed you use a UUC dogbone instead of the stock linkage. Doing a search on this subject, I noticed that in different posts, you mention the length you chose as 140, 143 and finally 144mm. But when I go on the UUC web site, I only see a 147mm.
    http://store.uucmotorwerks.com/short-shifter-kits-ssk-and-dssrs-c506all.aspx

    Is there a 144 hidden some place or would this 147 give you a little more room to avoid having the reverse hitting the shifter console?

    Great job Steve.
    Just hope you don't get noise from the 5 speed transmitted up through all that metal.

    Sorry, ordered a 144mm DSSR, contact Christopher Bethel <bimmer95@yahoo.com> to see if they still have them. From my receipt:

    Description

    Unit price Qty Amount
    UUC Double Shear Selector Rod | DSSR-144 | Stock
    $129.00 USD

    And the thing is so f'ing awesome. Fits and shifts perfecto. Way better than the stock one-sided rod.

    No noise, I have as much isolated with rubber as possible, maybe a little more vibration when holding onto the knob at speed, but this could be from elsewhere. Shifts very crisply and would do it again!

    Nothing beats having your transmission on a table...hope to be able to do the UUC connection someday.
