I have the aftermarket S.S. trim installed on the 52.
there are pics in my photobucket (page 3).
Fit was good and it seems of decent quality.
One tip I found that helps considerably, I took a pc. of scrap carpet and layed my window glass down on it and installed the rubber gasket an worked in the S.S. Trim including the S.S.Center strip on a sunday and let is just set there durin the week while I was workin.
That helped all the pcs. kinda conform an get the shape they needed and with a partner (my son) the next saturday we just picked it up as a unit and installed it...went pretty smooth.
