67 Barracuda Cat Whiskers

Hello fellow gear heads, hope all is well with all of you first and foremost. Question, does anyone know how to replace cat whiskers? I'm guessing all of the years btwn 67-69 is same. Mine is the 67 Barracuda and could not find anything on this topic. Also does anyone here have glass run weather strip for sale? Any info will be greatly appreciated as alway's. Thanks.
