Of course, I don't quite know what you mean when you say,
"they are not going to work for me the way I want them to", so I can only speak to my own experience so far. As I've mentioned, I just happened to have this old CPL sitting in my drawer and I got it to fit. The metal bezel of the CPL measures an O.D of 32.28mm with the actual front glass surface of the filter measuring only 25.58mm. On the back threaded side the I.D. of the threads measure just about 28mm and so it just makes it around the outside of the len's front bezel allowing me to glue it in place with UV cement on the outside of the lens housing. This is important because you want to be certain to avoid doing anything with the UV cement that might impede the ability to zoom the lens in and out.
I was surprised to discover that this 30mm CPL only has a glass that measures 25.58mm in diameter and I don't know if other similar CPLs are the same but I have not had any issues with vignetting. I would think that a 37mm CPL with 28mm threads should and could be made to fit this lens just fine but I'm saying that without knowing what it looks like. As for
@Harsh's 24mm CPL working without vignetting, I too am skeptical that it will work and I am now wondering what the actual diameter of the 24mm CPL's glass is but we'll have to wait and see what he reports back. One thing about the CPL I installed compared with the style Harsh has in that mine is fully mechanically adjustable even after gluing it to the bezel of the lens which has been a big plus here. One reason I seem to have obtained such good results with this CPL is that I've been able to drive to an optimal location (supermarket parking lot) and hook the camera up to my 7 inch LCD monitor and "tune-in" the CPL to my precise preferences for eliminating windshield reflections from cars in the FOV as opposed to internal windshield reflections from my own vehicle. (although there is some beneficial overlap anyway)
