[Mgs] MGA spin-on oil filter

[don]

The PO of my Mk 2 put an adaptor kit so that it now has a spin on oil 
filter.  I want to change oil and filter, and need to purchase a new 
filter.  Any recommendations for brand?  And more importantly, does 
anyone have a part number for a replacement filter?  The one on the 
car is a Carquest 85516, but the parts place I just called doesn't 
have a cross reference for this one.
Thansk!
