10.
Fit the two parts of the linkage knuckle around the
factory shift linkage with the long side facing up (fig.
11). The top of the long side should lean towards the
back of the car. If it leans toward the dashboard, turn it
around the other way.
Place the two M4 screws into the holes and screw them
in until they are finger tight, making sure there is an
equal gap between both sides of the two parts.
11.
Now loosen the left screw just enough to allow the
knuckle to be rotated horizontal (so that the two ends of
the knuckle are parallel to the sides of the shift linkage),
but DO NOT tighten it back up just yet.
12.
Fix the two side plates to the linkage by first inserting
an M8 screw through the plate and then through the hole
in the shift linkage fork. Thread an M8 nut partially on,
but DO NOT tighten yet. Repeat on both sides (fig. 12).
13.
On both side plates, insert an M5 screw through the
matching 5mm hole and thread it into the linkage
knuckle (fig. 12). Now tighten all screws and nuts. As
long as the lower M4 screw on the linkage knuckle was
set to the right distance as per step 10, you should only
have to tighten the top screw to clamp it up tight.
14.
At this point it is necessary to lock the reverse cable in an extended position in order to be able to
replace the roll pin. To do this, pull on the cable and simultaneously twist the linkage clockwise, then
pull it back to select reverse. You may need to vary the distance you extend the cable to properly select
reverse. Once reverse is selected, the reverse cable should remain extended when you let it go. If you
have difficulty at this point, it may help to temporarily bolt the linkage to the gearstick (as shown in
figure 13) and use the gearstick to help select reverse. Make sure to leave the linkage in reverse until
the end of step 17.
15.
If you have used the gearstick to assist in step 14,
it’ll help to unbolt it for this step. Slide the reverse
cable up into the top half of the gearstick. The hole
in the swage at the end of the cable should line up
with the slot in top of the gearstick (twist the cable
or rotate the gearstick if necessary). Line up the
hole in the reverse lever, then push the longer of the
M5 slot screws (the one used in step 4) through the
reverse lever, the gearstick, into the reverse cable
swage, and out the other side (fig. 14). This step will
line up all the parts and helps to guide the roll pin in
easily. If the reverse cable does not reach high
enough to push the pin through, re-check step 14.
