I've got a '62 also, N78987, based in Anchorage since '62.
I put on the Champion spin-on kit with the 48110 filter.
I like that the vernatherm screws into the unit.
Have had zero problems with it in 15 years, but a bit messy when changing filters.
I now change filter when eng is cold and set overnight so filter is not full. Seems to help the mess.
It's easiest to change when cowlings are off and top cowl is lifted at the back.
I've changed it through the cowling doors without uncowling but I usually skewer my finger with safety wire...and more messy.
Hope that helps...happy Mooneying.
