One last go at roof rail seals

Player,

I'v played with the rails (channel) for months trying to get a feel for corectness. I placed them close to where the manufacturer (Chrysler had them) based on the recesses in the channel, needless to say, it worked for the original rubber but not when I put the seal in the channel. I have adjusted the windows so many times. Did he Steel rubber sit flush in the top of the stainless steel channel. The metro did not, so I did not glue it. Before I installed the windows I put all new roller in. When I got the left rear quarter window in, I found that it moves up and down, front to back a (little sloppy), 3/4", the right however is good and tight? Got any suggestions? I probably will end up removing the window and re-checking all the rollers and other parts, right, I already know what you may say. Any suggestions will really be appreciated. I need all the help I can get. Sometimes what seems to be the simplest turns out tobe more difficult. Thanks for your help from an old man.
