I recently purchased a set of window felt guides for my 64 c1 from calssic parts. Needless to say they have been installed for a month and are completely bleached out grayish white from the sun ( they were originally black). I called classic parts and complained about the poor quality and they requested a picture, which I sent. They called me back and offered to send replacement felt guides. Time will tell if they actually replace the parts and if these replacements are any better quality. They claim that this is the first time this has happened...yeah....right. hopefully they do make things right as I have spent alot of time and money so far on just weather stripping for this build. I know that almost all of the repop parts are made in China, but they also stated that these specific parts are usa made and that they will find a different vendor. Precision is a USA company that has had booths at several of the show I attend yearly. I have a call into them for parts as well. I know that they are a true USA mfg.
