thanks Charlie ! that will save a couple of bucks for docs, medicine, and hospital visits.
i'll just have to hit the books to find something. there has been an old fram "chrome can" filter [new in the box] sitting on the shelf for years, but i don't like those things. never really have. it came with a bunch of other swap meet "stuff" probably 30 or more years ago. i just haven't gotten around to tossing it yet.
