Subject: [DML] upgrading AC accumulator

I have an earlier style (non-corvette) type AC
accumulator. Since the the system was at atmospheric
pressure (open) when I got the car, I'm considering
replacing this component in an effort to get the AC in
proper working order. Is it possible to update the car
to the newer style accumulator? I imagine I'd have to
get one of John Hervey's longer spliced line hoses,
which is ok because I'm considering replacing the
lines anyway (if they prove to have leaks, otherwise
the cheaper solution is to just replace the old style
accumulator) 

( Kevin, Hoses have to be special made to get away from the 
tube off the bottom of the dryer.
Are you staying with R12 or changing to R134a.) 


But what about the high pressure switch and relief
valve hub assembly I see on the later VINs? There's a
port on the later accumulator for the high pressure
switch, but where would the wiring go? (As far as I
know I only have wiring for a low pressure switch)

( Look for the rust around the connection on the hose coming from the
condenser to the evaporator if you have it. If not, then the hub assembly I
make would be nice addition.
Sight glass, high pressure pop off valve, binary switch, lines replaceable
where as they aren't on the original.) 
 
 

Also, how robust are the evaporator and condenser
coils in our cars? Should I be worried about replacing
them as well or are the hoses and gunk build-up on the
coils a bigger issue?


( Just be careful when changing out the orifice tube. They were put in at
the factory and then the tube had to be bent to go around the accumulator.
Normally the condenser and evaporator are good.)
