FOOOOOKIN HELL! What a difference,
Heres my experience....
So undo the clip on top of the OEM pin, lift the linkage off, Move it to the right and it will naturally fit firmly against the original pin, ease it over about another mm, Draw / score a circle from within the hole in the linkage, move the linkage back out the way to the LEFT side of the OEM pin, Drill the hole, clean area down, slide the sleeve, into the linkage, washer and bolt through that - position linkage over hole and feed bolt through, washer, loose nut, NYLOCK nut and tighten till happy, but not overly...
Here is my sleeve before I trimmed the ears off and hammered into the PERFECT sleeve!
Note I did this with the mechanism in situe, and had the nuts on the UNDERSIDE.. actually looks neater than having a nut up top IMO.
We tested it WITHOUT a metal sleeve, and as the 8mm thread is narrower than the linkages hole, the shift was just FAIRLY precise, SLEEVE added and 100% better and feels factory made.
Result?
The only car Ive driven with a throw as slick is my mates 500BHP Pulsar with a £2k Quaiffe gearbox...
Not notchy, just precision.
