I am in the short rows of finishing up my custom 53. I have installed the seal in the windlace. I have the outer seal and I think I want to use it. Couple of questions. First....I don't recall ever seeing this seal on any trucks at shows etc. Do people often just leave these seals off or did I just not notice them?? Second... several years ago there was a very good post on Stovebolt showing the correct way to install these seals....can't find it....please help. sojo
