I know this is an old thread but this is some of the info. I was looking for. Mine are green and a little dim. I love the blue ones Gary has. Thank you Gary for this forum...
I found green filters in a medium duty truck [F600/800]. All of the ones for F100, 150, 250, 350, that I have seen are blue and normally opaque [due to age]. The green ones I found are crystal clear if you want to stay with green.
