Using the very reliable search box (the one on the left side of the screen here), I found very good info from 2013.
Best advice I found...make sure ALL three points are in neutral before you ever start any adjustment of anything. I just did my 51, struggled with it, cussed it, threw stuff, and THEN did the search.
Make SURE the transmission is in neutral (BOTH levers on the trans cover being in the middle click position), make sure the shifter is in neutral, and make sure the shift box on the steering wheel is in neutral. Loosen the clamps on the shift rods so there is plenty of slack for them to move up and down. I took the cover off the shift box to watch it and you will see when it is in neutral (both the upper and lower shift gate will be lined up with the shift tab....which will put the two arms coming out of the shift box right at parallel with each other). I also put new bushings at the ends of these two arms. A standard rubber grommet works perfect on these.
Once all of these three are in neutral, carefully slide the clamps up (or down) the shift rods so the clamp bolt fits each respective shift box arm, making sure nothing moves as you do this. THEN you can tighten the clamp bolts.
Before I got to this point, my shifter was stiff, and it wouldn't go all the way into 3rd gear. No growling or grinding, just didn't engage. But once I did everything, according to what I have above, it all works as it is supposed to. Shifts smooth and goes into each gear correctly. 'coilover' is right though, you ain't supposed to speed-shift these. Shift it using the pattern as it was designed.
