Heater Matrix Replacement

Heating on 1998 Scorpio 2.3 Ultima had been progressively getting worse just in time for winter!
Thought I'd flush it through but on trying to complete this task the plastic was so brittle on the entry/exit pipes from the matrix that one of them has broken clean off!
So now I need to replace the matrix and being a climate control vehicle it requires the 285mm matrix and have been reading all the heater matrix threads on here to et some tips on the job.
Ford want silly money and even at fordpartsuk it is £176.
I have found this one for this very good price:
http://www.aaronradiator.co.uk/products/Heater_Matrix_Ford_Scorpio_Mk2_9 4_6FD104-11011-258.html
Just wondering what people thought and if there's anything else I might need to buy to complete the job?

Be very wary of doing the job. I have done in the region of ten matrix replacements, all for SPICKIES SCORPIO . It requires a complete interior dash and centre console removal. Please remember when these cars were built they did not intend them to be taken apart, therefore it is easiest thing in world to snap plastic fixings.

… and be prepared to have some left over screws and bolts if you forget where they came from 
Took me 3 days to take apart and put together again but, when I got to it, the matrix was a simple 2 screw 5 minute change over

Having difficulty getting to the matrix. Initially tried the heater box removal but this would not move as I cannot get the main vent pipes off so went for the brake pedal swing to the right way but find the steering column is in the way with this technique!

Sorry Scrappydoo but as i said in previous post removal of dash and entre console is only way. Using this method i could do a change in approx 4/5 hours.

Dash is all removed and heater box is out and matrix out but the matrix was the wrong size. Can't find anyone outside the dealer network (and over £150) to sell the correct sized one so sent the one I had back and will be dremelling the heater box tomorrow to enable fitment of a sierra one I got for £25 from local factors.
Tried to get new clips for the heater ducts at the side of the box that goes to the rear passenger areas but they can only be ordered in batches of 20 and they're £2.50 each! 
Another thing I can't get is the gasket for the bulkhead faceplate for the matrix pipes, will have to bodge the remains of the one I've got.

Gasket for the bulkhead faceplate can be cut from foam sheet available from craft shops such as Hobbycraft

Right an update!
Matrix now replaced and heaterbox refitted. Managed to reuse my old faceplate gasket via superglueing it back together! Also managed to find the rear passenger duct retaining clip centre pins too, so no need for any new ones of them either. Only issue is in order to get at these clips I've had to remove those ducts completely from their positioning but on attempting to refit them I'm struggling!
Does anyone know where and how the rear passenger ducts that attach at the side of the heaterbox fit? I'm struggling to refit them beneath the carpet...the diagram I've seen on the sites matrix how to seems to show it fitting into a bracket under the seats but I'm fairly sure these don't as they haven't got the bend in the pipework to do so!

Mine are just as shown in the diagram:

Run under the carpet along the side of the transmission tunnel then to the middle of the footwell & push into the box section under the seats.

Dave,
So I take it there's a hole in the carpet on the tunnel where it can comes back out under the seat? Haven't been able to locate that yet.

Hi Simon
In front of the seat the heating trunking stays completely under the carpet all the way from the heater box to the steel box section under the seat. The carpet goes over the steel box section & is cut along the rear edge of the box section. The trunking protrudes a little through the box section into the rear footwell so the rear part of the cut carpet tucks under it.
Hope that makes sense.
Dave

Should be easy, as far as I remember it just lays on the floor & is a loose fit in the hole in the box section.

The box section is part of the floor & goes from the side of the car to the tunnel. If you get in the back of the car & look under the front passenger seat this is what you should see:

Dave, Great picture and I know exactly what I'm aiming towards now but I still cannot see how the ducts can be routed towards that under the carpet though!
