Well Alvin that I DO NOT KNOW.. it lookin to be wider ? ..it is the S.S.Trim from Classic Parts & supposed to be the same as factory ...BUT WE ALL KNOW HOW THAT CAN BE!...lol
My 52 didnt have that trim when I got it so I have nothing to compare it to...I just threw a set of calipers on it ..it measures just shy of 9/16 of an inch wide.
The trim was onna my easiest installs as far as glass went ...an it looks darn nice compared to the plain rubber gasket in my opinion.
