Repairing 2017 Flying Cloud 26U

[jp77texags]

Hi all, I just upsized to a 26' from my 19' Bambi that I still need to sell.
I just bought this brand new 2017 26U Flying Cloud today, from an auction company. It needs some work, so looking for advice from yall gurus.
I need to replace the front curb curved window, its plastic protector, and front alum. curb side Rock guard.

Question, where is the best place to get these parts?
How hard is it to replace them?
Have to drive 1200 miles to get it this weekend.

thanks in advance for all advice.
