hello , I am restoring my 60 pioneer wagon and cant find quarter glass seals , none reproduced yet and no old stock available, any ideas of what will work to hold quarter glass to body, mine are too cracked to remove so i can paint car, and too scared to remove them because i might not be able to put them back in lol. any help would be great , even if i have to not use the quarter glass molding. thank you jack .
