Paul,
I have everything out as the whole car was stripped. My heater went in
easily enough without the seals. The seals I got from LBC Company in
Detroit and the one that goes around the fan hole was foam. This is stuck
to the hole with contact glue as getting it right without it being held
seemed impossible. The other seal was a thin rubber/vinyl one that went
between the body and heater box. I stuck that in place with Dum-Dum which
has the added advantage of filling up the gaps between the faces. I think
sticking the seals on before fitting is the way to go. The box went in
before but would not when I attached the cable. It rubbed at the back - see
photo. I assumed it would go in so I did not try. Now I shall try
attaching the cable through the vent - arrrrrhhhhh. My 1970 shell seems
to have a bigger vent so maybe I can get my wife's to do it (dream on).
WAIT
HAve just had some more info come in - and damn it they seem to have had no
trouble with it!! I have an idea that maybe the cable lever has to be in a
certain position to go in - either fully open or fully
closed.................will try that !!

Hi Barrie,
First, there should be a secret handshake for those unfortunate few who have
had to R &R an MG heater box!
I now wish I had taken a photo of what I did, but basically I could see
where the cable was binding as you have. You can eyeball or measure if you
want, but the main thing is that when the box is installed the slot you
grind is vertically in line with the cable lever when attached to the flap.
In other words, you don't want the slot to veer off one side or the other
because the whole purpose of the slot is to be able to accommodate the cable
without bending it as the box is lowered.

With the heater box resting on the valve cover/bulkhead, you can reach in
behind the box and feed the cable into the hole/shot. From there it goes
through the small hole you marked. As I recall I don't believe it comes in
through the rectangle hole, but rather feeds up and over to the control .
Looks like you're doing a beautiful restoration!
Hope this helps,
Mike
