Radiator Fan Switch Info

[derf <derf247@gmail.com>]

Anyone know how to find specs for Wells parts?
I have a few leads for fan switches but I would like to know specs for the
following Wells part numbers:
TU66
SW501
SW502
SW518
SW532
Anyone got a hookup at Autozone?

Or, anyone know of a 180degree radiator fan switch with 3/8 18 threads?

Anyone BTDT have any suggestions?  I don't want the probe in the radiator
fins or an adjustable setup.  I just want a simple switch, relay, and manual
override setup.  I already have the relay and override covered.
