    Question Any interest in aluminum shifter bushings (in lieu of the "Home Depot mod")?

    My car's at a shop now getting a new slave cylinder, and while the transmission is out I snagged the shifter mechanism off of it to do the "Home Depot mod" with the plastic bushings. A couple days later in a thread on corner-carvers.com I saw pics of a GT500's shifter mechanism with aluminum bushings installed. I'm not sure non-members can see the pics on cc.com, so here's how they look:






    (That's actually a Boss 302S transmission in that last pic, but you can see it appears to use the same type of pin with the locking clip on it to attach the forward end of the shifter arms to the transmission.)

    I PM'd the guy who makes the bushings and he said the measurements don't quite match up. However, if there's enough interest, he said he could do 10 sets or so for the CTS-V. The GT500 bushings go for ~$60, so that's what we'd be looking at.

    My guess is most folks will be happy sticking with the "Home Depot mod", but I figured I would post up and see if anyone was interested.

    I think we got lucky with the Home Depot stuff but just saying that out loud makes me cringe...

    Frankly, I don't think you're going to beat the Home Depot bushings. They're 48 cents. And they're ABS plastic. There's nothing left to gain there, except NVH. However, if there's a chance he'll make a center shifter linkage arm with a better coupling to the transmission that doesn't require that stupid pin, I'm all ears.

    I can mimic those, but like they said abs plastic wins hands down...Price and ease of replacement are better

    I'd be in for a set.

    If you give me the inside diameter of the linkage arms, I'll make you some. I think that's the only dimension I didn't measure the last time I had mine out. I have the stock rubber bushings but I don't trust that dimension. I'll make you some way cheaper than $60.

    I took some measurements earlier. Sadly, I didn't get the inside of the cup, but I got the outside of the OEM bushings. Therefore (as you previously said), I would take these with a grain of salt. As I recall, the OEM bushings are lightly snug until the metal core goes in. Then they fit pretty tight. I also found that the Home Depot bushings varied by a fraction of a millimeter, so I ended up throwing throwing one or two away before settling on the ones that I installed.

    I had to lightly tap the Home Depot bushings into their mounting ears on the T-56 with the aid of a rubber mallet. The T-56 mounting ears are probably 0.1mm smaller than the installed Home Depot bushings.

    Unfortunately I have all those in the pics above. I need the inner diameter of the arms. I suppose I could go to Home Depot and measure one of them.

    Would brass be more appropriate than aluminum for this application? I'm thinking of galvanic corrosion (carbon steel + aluminum = no thanks) - I don't know what the arms are made of but just guessing.

    And longevity, perhaps. That's the only reason I would consider going this route - I don't know how long anyone has had the Home Depot bushings in there.

    One that could be turned from aluminum on a lathe?

    There shouldn't be any need for replacement with aluminum, so I would hope that would be a moot point.

    The OD of the grey plastic box adapters is ~21.4mm with old school vernier calipers (none of this fancy digital stuff ). In my experience they slipped into the shifter arms pretty easily (no interference at all, really), so the ID of the shifter arms is probably in the 21.5 - 21.75mm range (just guesstimating).
