Anyone know where I can get a new filter that goes on top of the trunk mounted ac on a '55 buick. My parts car i bought has a/c and I'm installing it in my car. The bad part is it looks like about 15 years worth of mice made a home in the unit and it looks pretty bad. I stripped it down, cleaned it up, and repainted it, but the filter is nasty and can't be cleaned. I've been trying to find a replacement with no luck so if anyone here has any suggestions it would be appreciated. Thanks
