I was looking at a friend of mine's plans for the edge pirhana and it has details of shortening the escort rack and a holden one also, I assume you need to take it apart shorten the outer tube, shorten the inner shaft drill and tap the end then re assemble.
Do you have an escort rack, are you in the UK?

Doug Hiem has some innovative methods of modifying a R&P - even one with power steering. Keep in mind, all you need is a strap-down style rack/pinion. Many small cars use the same design with few variances in length and pinion angle. The cup and ball end have different means of thread locking. Mine was a machined flange around the stem of the rack. I had to carefully grind this down to be able to unthread the cup. I spot welded it back after the mods. Doug chucks up the entire housing assembly and neatly turns a round edge for the left side bellows to clamp onto.

There is a site on Ebay where you can get these newly remanufactured for 30 bucks each.

Here are snapshots of mine...it worked great!

This bottom pic shows the 1986 Hyundai Excel rack installed with a straight pinion.
The other R&P is from a mid-70's Dodge Colt. The pinion is slightly angled but will work fine also.

Man seems like a ton of work when you can just buy one for 100 - 150 bux tho, I guess it is about self gradification sometimes tho...Looks like yours turned out well rxpo, When you coming up riding anyhow, there is talk of a Silver lake trip in the first part of October...

I was gonna say that the pictures above look identical to the Hyundai rack I just modified. I just went through this and finished it on Friday! It is amazing to see the pictures of what I was just working on, on the net.

The only difference between the pictures above and mine is that I modified the length of the inner pivot points to exactly match those of my a-arms (23"). The only problem I am left with right now is that the old protective boots will no longer cover the joints without leaving the the rod exposed where it comes out of the center rack.

Also, the pictures above do not show what was done about a bushing, or a guide, for the side that gets cut short. Need to have something over on that side to guide the rod. Maybe the one in the pictures has it, but it was not discussed, or shown. I found a steel bushing that was the correct ID to work with the shaft, and then welded that onto the end of the tube where I cut the other end off. I did not cut it flush like the one in the pictures above. I specifically left 1/2" of metal exposed to be able to weld the bushing to.

Also, if anyone else is going through this, I found that 1 3/4" exhaust u-bolts work perfectly to secure it to your frame. The u-bolts for exhaust come with a little bracket that is already half-mooned for holding the rack. I simply welded the brackets to a flat steel panel, then drilled holes for the legs of the u-bolt to pass through. This will allow me to rotate the rack to get the perfect alignment when the time comes to attach the steering rod to the rack.

I'm hoping that when done, the number of steering wheel rotations to turn is not excessive. If it is, I'll have to incorporate a steering quickener.

You may also want to dowel your rack to the frame.(If you are only holding it down with U bolts.) My first Piranha was set-up with the U bolts and after a few trips to the dunes it became loose. I tightened it and on the next trip it actually sheared a U bolt right off.
After that I drilled up through the lower frame into the rack housing, then drove a pull dowel into the unit. The dowel now takes all of the side loading. Without the dowel the side forces may eventually cause the U bolts to fail. Just be careful not to drill too deep into the housing.
I had milled a portion of my rack flat on the bottom which set flat on a mounting plate.
This is where I doweled it.
