I found electric power steering kits that go between the steering column and the steering box so you keep the steering box. Even easier to get power steering

Now I like the sound of that, where does it come from? Does it need speed sensor's etc..

edit: Just googled Electric Power Steering, found that one and many many more. I didn't realise that this had become such a big market. It looks like a very doable conversion using the existing column if you can find space for the motor to mount.

That looks good but I wonder what thpse thin wires are for, if it is for any sort of CAN bus/ECU then screwed.

There are kits out there that give you everything so no worries.
There is more that comes with that unit. I just didn't post it all.

OK I think I discovered the closest thing to factory R&P for the bug.

Mounts are narrow enough to fit on the frame head and its narrow enough to fit between the shock mounts. I know it isn't a center take off for the tie rods. Sometimes you have to take what you get and make it work.

I'll post dimensions later

That is near enough the same as the Citroen C15 one Scorpion and I are using, overall needs to be 1100mm so 85mm (3.3") of each end and re thread will do it UNLESS they are right and left threaded, in which case it might be a problem getting a LH threaded die but they are about. Mounts look near the same only saddle instead of single bolt.

After researching steering geometry and learning more about it I'm at a cross road as to whether to do it or not. As you can see from my posts I've kept moving forward with it.

Steering geometry is going to change with installing the rack and pinion unit and I'm not sure if its for the good. Bump steer may be more of an issue I think when installing the R&P, plus the tie rods on the R&P will be at an angle for them to connect to the mount at the spindle. If you look at vehicles that come stock with R&P the rods are about at the same alignment as the unit itself not at an angle as they would have to be to connect to the VW spindle.

Another thing I've noticed is, in the stock configuration the pitman arm travels in an arc to turn the wheels. With the R&P it travels in a straight line and its not aimed at the connection point at spindle as it does in vehicles that come with R&P. What does this all mean?? I don't know but I'm just trying to eliminate any issues before they happen.

Yes I know alot of these conversions have been done but was it worth it.

OK here's a good thing(I think) with installing R&P

There maybe a safety outcome.
With the stock setup the steering shaft is aimed right at you so if you should ever get in a front impact accident you could get the steering shaft shoved into your chest

On the R&P the connection point is at an angle providing a deflection point, also the R&P I have has a small collapsible section to it providing more safety

I fitted R&P to my first Nova, I mounted to the R&P as low down as possible on the frame head so that when the car is on the ground the R&P arms are practically horizontal, thus removing some of the effects of bump steer.

I have driven quite a few miles with my set-up since I installed it about 20 years ago and I can't say I ever remember noticing bump steer whilst driving. I'm not saying there may not be some there, but its not enough that it has ever stuck in my mind. And yes you are quite right, having two offset UJ's as part of the column means it won't push the column into your chest if the worst occurs.

'Ats right David, I always had misgivings about the OEM steering in a shunt. Like most R&P converts I have a angled joint at the bottom of the column and in my case a sliding shaft in the Triumph column too.

As far as 'bump steer' goes I haven't noticed any, just nice smooth steering, in my photos the arms look as though they drop down but that is because there is no weight on the suspension, under normal load they are straight. My rack is 3cm above the frame head and 30cm forward of the cross member.
A slight back angle is desirable because as you say the track rod moves in an arc and fully out will be almost dead in line, starting out in line means the road would be forward of the rack at full stretch.
As you know, the amount is important for the Ackerman steering where the inboard wheel turns more than the outside wheel.
