I thought I might aswell show what i'm doing with the gearstick part 2 as i'm ill and can't lay in bed doing absolutely nothing so this relaxes me.
I want to extend the gearstick length even more as I want it closer to the steering wheel further more. The current one I have is from a Renault Scenic which is extended already.
The best way to look at the gearstick is that it's made up of two pieces;
1) The inner rod - this connects to the pivot inside the housing and the bottom pivot bush to the gear linkage
2) The outer shaft - this is for the lift up reverse as it's attached to a collar that lifts up and allows you to get into reverse by lifting over a plastic junction.
This is mine. The outer bit is plastic and has way too many ridges and doesn't look great. I'm also really not a fan of how you can see the inner rod (the bit inbetween the outer shaft and the gearknob) so I will be dealing with this later.

First of all i'm going to extend the inner rod. I'll do this by drilling the original inner rod from the top down and then tap an M5 thread in it. I'll then screw an M5 flat ended grub screw into that by 15mm, with loctite.
I've ordered some 12mm rod which I will also cut down (dependant on how much I want to extend it by) and also tap that to M5. This rod will then screw onto my inner shaft extending it. Done. Did a little pic to explain what I mean.

This pic shows where I need to think of an idea on how to attach the lift up reverse collar at the bottom right with the cable attached to it, to my rod that I have. The OD of the plastic will fit in my ID of my rod, so maybe epoxy resin, but I don't like the idea of that I really want something more secure.

Now coming back to how the inner shaft is visible. You obviously cannot push the gearknob further down as the lift up reverse needs to... lift up and it will collide with the gearknob.

So my plan is to have the rod inside the gearstick like this...

I will drill out the bottom of the gearstick to 17mm (the metal tube i'm using is 16mm) so it will fit nicely inside.
However I need to know much as I don't just want to drill and drill as obviously the gearknob needs to grip onto the shaft. This is determined by this length here, getting the verniers right in.

17mm.
And a little trick if you want to know the distance of two holes from each other.
Measure the diameter of the hole as shown here

5mm
And take away that diameter from the distance. 17-5 = 12mm of travel.
Just to clarify that I looked at the top and you can see where it has scraped and measured that.

So going back to this image, I now know I need to bore out 12mm of material from the gearknob for the travel of the lift up reverse to work if I want the outer shaft to be located inside my gearstick.

I then needed something to grab on the shaft for the lift up reverse for the drivers hand side of things, so got a 17mm shaft collar. 17mm ID, 28mm OD so plenty to grab hold of.
But yeah, I just need to somehow attach these parts together if anyone has any ideas?
