I got the shifter socket and the shifter bushing from Marlin Crawler, and I agree with Wingman to an extent...
The shifter bushing is waay too tight, and since it's made from delrin it doesn't bend into shape. I had to cut mine in two with a razor blade just to get it to fit, and even then it binds too much.
The Toyota green bushing is great, but it seems to me that they get sloppy rather quickly--at least with the sogi mod. I've replaced the green bushing twice in the last 60k miles...
If the Marlin Crawler bushing replacement is the only option, I'll probably tinker around with it some more, because it wasn't expensive at all...$10 for the shift lever bushing, and $6 for the shifter socket bushing.
Anyone know of any better solutions?
