2015 Redwood 31SL Bedroom slide seals.

[Cindy & Ray Keen]

I need to replace my top outside and inside bedroom slide seal.. I was looking on this forum and I found some info. The wiper seal calls out an AP 018-413-BLK. I cannot find that part number anywhere online. I do not know if it a typo or what. Anyone with any ideas or replacement part numbers or even an aftermarket seals I can use would be helpful also. I did order the D seal AP 018-312-EKD BLK. Thanks.
