Just out of curiousity... is it OK to use "NOS" fuel/oil filters? I know they're unused, but is the paper elements in 35+ year old filters still up to the task of being actually used as a filter after sitting in a GM box for that long? I'd think there'd be a potential for the paper to be dry rotted and crumble apart as soon as oil/fuel passed through it... Although the one I used was an old NOS piece and seemed to be ok.
