I've rebuilt the one in my '50 a couple years ago. I don't know how similar
it is to your '59. I got the rubber washer from an ad I saw in Hemmings.
The washer was about 12 bucks. It's seem to be the same for a variety of
makes, including my '89 Volvo, maybe you can find a cheaper source, though
I wouldn't try Volvo. The thermostatic controlled bladder moves very
little in my '50, 1/8 sounds about right. I checked mine by measuring the
thickness at room temp and in the freezer.
