Hello to all soldering/brazing experts.

I am trying to add an AC unit into my 1982 diesel Westy by using the roof
mount evaporator unit out of a 1985 van. The unit sits right behind my head
(when I relax in the seat and imagine that I am actually driving), but with
no modification will stick into the pop top hole. I was going to disassemble
(OK, I have already disassembled) the ducting and make the unit a bit
"smaller". In order to do this I need to change where the hoses come into
the evaporator. There appears to be some sort of plastic coating over the
copper, and it appears that coating would remove easily. I am curious as to
what I should be looking for in terms of solder to properly reattach the
ends once I have them where I want them. What is proper AC type solder?
