I've checked with the local AutoZone's and O'Reilly's but none of them could get the Art Carr thermostats. All they could get where the smaller holed ones stamped with 54mm on them.
I purchased a thermo housing from a fellow board member that had a 330-180 thermorstat in it. The opening was a lot larger than the replacement ones from the local parts store and all brass.
I ordered the Mr Gasket 195 thermostat (p/n 4365) from Summit for approx $8.00. It looks identical to the all brass Art Carr and has the large diameter opening.
