Spin-on Oil Filter Adaptor

["Sumner Weisman" <sweisman@gis.net>]

O knowledgeable ones....

I want to take last minute advantage of the TRF winter sale and get a
spin-on oil filter adaptor and avoid the annual Spring mess on the garage
floor.

There are two -- Purolator and Tecalemit.  The catalog says that one has a
fine thread and one has a coarse thread.  ISTR that mine has a pretty fine
thread, but that's not a very positive way to define it.  Are there any
other differences that I can check, such as a difference in color?
