[Gmcnet] Duracool compatibility

[Mr.erf ERFisher]

you have to check again, it is approved when changing from 134 to Duracool.

so put on the 134 connectors that gets you from r12 to 134, then fill
with Duracool and go for it ;>)

oh yah, recover the r12 if there is any remaining, ( which there prob.
is none in a 30 year old system).
