i'm ordering mine from a linkage shop online. M8x1.25. LH threaded on one side, RH threaded on the other. They have them in every length, in 10mm increments. They're about $5.50 plus shipping.

They have just about everything you need to make any kind of linkage you want.

Midwest Control also has all types of metric heim ends, if you want to upgrade from the standard clevises. They are very customer oriented, with usually no minimum order amount. Great to deal with. Regards, Chase

What would be the benefit of going to heim joints instead of clevises? I assume it's smoother action since it's a ball and socket joint?

The Heim ends greatly reduce free play in the linkage. Possible friction reduction, but that's difficult to verify. You may have to bush the holes in the shift arm and shift lever for a good fit with 6mm bolts. Regards, Chase

Thanks for the confirmation on that.

I'm trying to wrap my brain around which bits i need. The "threaded stud" goes through the shifter in place of the peg that holds the clevis in place, correct?

You mentioned 6mm, so i'm looking for a set of threaded heim joints that have a M6 threaded stud, pretty short and trim the length, that have an M8 threading on the housing end?

I know M8 is the stock threading for the shift linkage, but if i'm replacing the clevis joints, could i go with M6 on the rod?

Or is there enough meat on the shifter to drill out the hole to 8mm?

My fault, missed the 8mm rod spec (I've gone with 6mm). You should be able to drill out the shift arm and shift lever holes to 8mm. Then use 8mm bolts to attach your 8mm heims. Thanks, Chase

Thanks. I may try and tap the holes to m8x1.25.
