Yeah it's different in a mk1 but the same, as your MK2 has the wiper bolt up in the passenger side, mk1 is next to the heater and dash panel support which it's bolted to with 1 bolt, it relies on the arm pivots to hold it.
Today I got the motorbike fairing isolators so got them installed, also stuck a nice thick foam seal around the tube part so it's fully sealed from the outside. I think the foam was made for C channel in the building industry, weatherproof etc.
I think I'll need to pull the heater out again to bring the core further out, not a big deal but annoying .

Heater installed but had to run spacers so the core tubes weren't too high up

... And then I realised the cables weren't long enough about an inch so i ended up making me ones with sacrificing a non serviceable mk1 throttle cable and some Tig SS rods, it's as good or better than factory
I have removed and cleaned the switch face for the new sticker coming soon.
The switch cover is a test mule and might be binned after, it's not great on of finish. I had no idea that installing a early MK2 heater box was so complicated , only cause I didn't have a mk1 one.. you can see how close to the tunnel the lower plastic is .

The cables are pretty close to the heater vent , I might need to do some adjusting where I can either by trimming or 3D printing a special dogleg into the vent, dash vents are from a USA Ford F150 Lightning, they are the same diameter as regular Escort vents, I did buy a set of 4 vents and all have this silver and chrome, with the idea to paint a pr black with chrome rings to see which works best
