Now I know why it was so hard to get the heater core out, I could not get the new one in.
Ahhh the wonders of Phone technology, you can stick one of these any where, it will self focus, snap pics, giving results.
We have three layers 1. Outer case. 2. Firewall. 3. Inner case. The converter had applied (possibly under pressure) a rubber filler sealant.

Now this has set harder than the rubber in my tyres, and stuck with more tenacity than my tyres have on the road.

But the clincher - it had also permiated thru the holes and into and between each of the firewall layers, but after a scalple, bull nose pliers, cursing and threats it finally relented and came out albeit in small pieces. Wallah - how easy the core went back in - easy peasy - now for a lay down so my blood pressure comes back down. Or maybe a Scotch.

In your pic on page 1 the cavity where fan is drawing air from goes down under car & sucks air from under car & also from gap between body & L/hand bonnet catch assembly. I had to fabricate a duct from inside car to the fan to exclude hot air from under car & engine bay to make it truly recirc only

Ummmm... I'll get a brighter light and have another look, pretty sure mine has no entry for outside air.

And for those members concerned that this narative on the Matrix is lacking a character, I can assure you that Neo wanted to be involved but is far away practicing social distancing.

I'll now go double check my  openings, and then search for some closed cell foam to wrap my MATRIX, ready for re-installation.
Regards.

No - openings. The fire wall and bulk heads are all solid and sealed.

Could not get the casing back together with the new core fitted. It must be all put together on the bench and installed as a completed assembly.
I was going to cut the casing in half, but after a lot of thought, I realised the side where it was hitting would still interfere.
So I cut  a corner off the part that was hitting, with this done, goes straight in easy peasy. Obviously this will need to be patched later.

BUT ! There's always a but. Whilst it goes in easily - the RH side goes in and together perfectly, the LH side & esp where the case goes around the copper pipes will not go down to allow the mounts to come together, so as to screw up. Frustration reins suppreme.
The copper pipes cant be moved without running the risk of cracking the solder joints. So out it comes, start again....

I'll have to compare the old to new matrix's, whilst trying to refrain from smashing something.

The matrix conspiracy  is  becoming more of a covert operation.
