Bruce,
Take a look at the factory manual. They suggest you START at the upper rear corner where there is a gap in the channel, put one end straight down the rear of the door opening and the other end goes toward the front. I noticed on my 50 COE that there where restrictions every couple feet, like someone took a mallet and whacked it, to secure the windlace in the channel. Therefore, you need to take a couple inch length of your old windlace and run it through the channel so you can see where it binds, before you install. Then you take a screwdriver or other tool and open up that part of the channel. Lubricant of choice and another pair of hands helps, too. (No, I am NOT talking about that; this is a family forum).
