Rack is from a Mk4/5 cortina, but PS was a little rare on these. Try and find a high spec one thats breaking. Rack should fit with only a little encouragment, but you may need to modify the column slightly.
Use a PS pump from any Rover V8, and change pulleys if needed. You will probably have to fabricate pipes from the pump to rack.
Alternatively, why not consider an electric PS pump, i'm considering doing this on mine(Mercedes a class looks favourite at the moment)

It is only possible if your chassis is designed for it as on a no-pas chassis the bigger rack fouls the strut that comes down from the front turret. The Pas cars have a curved strut to provide clearance. As the strut is very important in preventing the turret from moving and cracking, not totally convinced that it is a good idea to cut and shut it.
The intermediate shafts are different and there have been about 5 different racks fitted over the years so... the mounts may vary.
The pump is a Rover Sd1.

I've done this to mine, I used a Mk5 Cortina power rack, in conjunction with a mkII Granada pump and hoses and getting the extra pulley for the crank nose off a SD1. I did have to severely modify the SD1 pump bracket and make a pulley for the ford pump, in hindsight it probably would have been easier to make new hoses and use the SD1 pump. Also finding the correct lower half of the steering column was a pain, for as Steve says several types were used. I got mine from David Gerald in the end and exchange it a couple of times and I still had to modify it slightly.
As to the chassis fit, mine already had the curved strut plus I had to 'massage' the big square rail a bit to get clearance for the for the rack. But mine has had some welding in this area which is probably the reason for this.
However the end result was well worth it, as the level of assistance is just right. One other thing to check if you have heavy steering is the condition of the bottom balljoints - tricky to check as you have to support the car on the wishbone to remove the spring force taking out any slack
Best of luck
