Question on slide seals

[clitesm]

Recently purchased a 2008 Palomino Sabre 28RBFWS and I've got a question on the inside seal of the full wall slide.

The part of the seal above the sofa & dinette is a hollow D-shaped foam seal about 1" x 1" glued/stuck onto the wall above the slide. There is no wiper on the inside seal (only on the outside seal). About 6 feet of the seal above the bed looks like someone replaced it with a somewhat narrower hollow P-shaped seal glued/stuck to the wall above the slide. The "leg" of the P is up, with the bulb down (think of the letter b).

At both inside ends of the slide, the seals are snapped onto plastic tracks screwed into the wall, and these seals have integral wipers. They also seem to be a non-foam rubber. The outer seals seem to be of the same type of construction and mount as these inner end seals.

Can someone confirm if the upper inner seals are the proper "factory" seals? If they are not, are these OK or should I have them replaced? Can anyone give me part numbers and ordering info?
Thanks!
