Default 1961 T-Bird Heater Core Replacement

Hi Guys!
I'm new on this forum and would like to share my experience replacing or fixing parts on my T-Bird.

First of all something about me:

I'm from switzerland so if they are some orthography errors please excuse me.
I'm 31 years old and I'm a happy owner a 61' T-bird Convertible since 1 month I'm a big fan of US-Cars since I'm 15 years old and my dream was to own a US-Car with V8 sound and my dream becames true this year

Ok, let's continue to the problem:

I changed the cooler tubes and had a leak inside the car after that. It was the joint of the heater core flange that was old and broked by changing the tube. I had some troubles finding a replacement manual so i decided to take some pictures and create something like a manual on this forum.

1st step:
take out the 4 screws for the side dashboard cover

2nd step:
carefully take out the trim bar using a big flat screwdriver

3rd step:
remove the 3 screw of the air conditioner ventilation, the screw of the trim bar and the 3 nuts on the back of the lower dashboard cover (in yellow)

4th step:
remove the 5 screws of the dashboard cover, the one right down is fixed with a nut

5th step:
remove this cable

6th step:
remove the 2 screws of the temperature wire, the 7 screws of the cover plate and the 4 screws of the feet air blower ( i marked only 2, the 2 other ones are not visible on the picture)

7th step:
remove the heater core by taking out the 4 screws ( i also marked only 2 because of the other ones are not visible)
D'ont forget to take out the water tubes inside the motor room

Then you can take out the heater core, unlock the 2 nuts of the flange and fix the leak. I fixed the leak problem by adding a thick silicone o-ring. first a cleaned the flanges with a metal brush, added some grease to avoid rust in the future and putted this thick o-ring. I tested and it did'nt leak anymore.

Hope this post can help one of you guys one day.

Oh, you can see the aluminium tape on the dashboard ventilation, i take a old bicycle hose and cutted it on the right size and fixed it with aluminium tape because i hadn't the correct spare part, but it also works
