Few questions about aircon and rear speakers

[The dutchman]

Hi all.
I have a \'92 touring fd.
It has climate control but its broken and after many searching on the net i found out that all the climate controls get broken and there are almost no replacement part for it. So we decided to switch it to a normal airo unit. Bu after removing the climate control panel we found out that the wires are different......
Do we have to replace the hole wire loom in the dashboard?
And are there other things different?  Such as the heater or so?  
I will need a new front panel i know that.

And my touring has no rear speakers but a little space  for storage.
Now i wanted to convert it into speakers but can i just pull the storage bins out and replace them with the speakersl brackets and mesh?
Or has the hole sidepanel has to be replaced?

Thanks for reading.

The rear speakers are in the rear side panels at each side
