You are needing what is known as several different names within the industry. Whether it be belt line weatherstripping, window felts, cat whiskers, window fuzzies or window scrapers, you are referring to the same piece that is the inner and outer seal for each door which basically keeps larger pieces of trash from entering into the door cavity at the same time that it finishes the edge of the door and helps a bit from the door glass rattling within the door frame.
Each and every body style have there unique style and as I said earlier, the Top Catwhiskers that we provide to our vendors will incorporate the same attaching clips and placement as your originals. We have tried to source what is the most correct material available to duplicate the factory originals. Some of the felts, we have been able to locate the original vendor for the material while some of them will vary slightly from the originals but will function as the originals.
For the 62 to 65 B-Body product line, we offer 14 different styles to cover the different variations within that time frame and body styles. No need to fabricate anything unless your looking to do something highly custom.
Give Joe a call as he should have some in inventory or drop me a message and we can get your needs covered. Classic carries a variety of vendors products and you have to specifically ask in some instances for a particular brand as the Top Catwhiskers. I know that they carry certain pieces of our product line as they list it under a 63 to 65 Belvedere under the Part Number MB1131 for the four door sedan application.
