It's just an aesthetic thing, the work will not be a problem.
As can be seen in these photos:


Nothing has had to be cut.
Main issue is that I cannot find the A/C manual for Sj413/SJ80 anywhere!
Incredibly odd move that suzuki decided that A/C wasn't important enough to be included in the standard FSM, it means that I cannot find any trace of this document anywhere online :/
I've found the one for the SJ70, but as you can see, it's definitely a different install.
