Fleetwood Fiesta Slide Bulb Seal Replacement

[fvrs7189]

Hello All,

I am getting my 2008 fiesta ready for the season and noticed that the bulb seal on the slide is starting to deteriorate on a few of the slides. I have purchased replacement seal that goes into the track, but since the tracks come to a 90 with the other track, how do you go about getting the new seal into the track? All of the videos online show Keystone's where there are external screws that take a corner cap off. I do not have any external screws. I do see screws up the whole side are are on the inside of the slide. Do these take the edge off at which time you can replace the seal? Any help would be greatly appreciated.

Thanks
