[VAC] Dometic Refrigerator repair

[Joe DeLillo <tooljd@xxxxxxxx>]

Hello Airstream lovers, I'm currently in the process of starting to
restore my '59 Overlander.  My first (and, I might add, my most
difficult decision) is to decide on keeping my Dometic refrigerator
which is original.  The unit is a gas only unit,  model #75A. My
question is: does anyone still repair these units?  I've heard that no
parts are available for the burners on these units because they are
ceramic.  The burner on my unit seems to work OK , but I believe that
the ammonia must need replenishing.  If that's the case, I must have a
leak in the system.  The nostalgia of this white porcelain refrigerator
makes me want to repair it or possibly retrofit a new style Dometic
refrigerator to the preexisting  stock refrigerator compartment.  I know
that some will call me crazy, but I want to keep this trailer as
original as possible.  I also need advice on the availability of the
stock paint  that was used on the walls and headliner.  This paint is a
"tricolor" spackle texture.  The previous owners were smokers and I
don't think the headliner will clean up as well as I would like.  Any
thoughts on these two problems will be greatly appreciated.  I read
these articles every night and enjoy them . I've restored small campers
in the past and my profession is in electric and hydraulic tool repair. 
I've never seen this kind of support among collectors as I've read on
this net.  I hope with my previous and future restoration experience I
can be of help to any Airstream owner out there.

Thank You,

Joe DeLillo
