Leer cap maintenance/replacement parts

I finally got my hands on a Leer cap for my 2013 DCSB, at an amazing price but there is some stuff wrong with it. I got it for an amazing price so I am not too worried that it is not in like new condition. I was going to pay $250 cash for it but ended up trading my canvas tonneau cover for it that I was looking to sell. When I got the cap I noticed a few things wrong with it. 1- the rear door window seal is damaged and missing bolts so it hangs down in the way of the tailgate closing, I can get both the tailgate and the window to open and close but it takes a second hand to lift one while the other holds the frame up. 2- the side windows t-handles are rusted to the point where they will not turn, not to mention they do not have the keys to lock. Wondering if anyone has any experience with replacing these handles and could point me in the direction of where to purchase them. Also in regard to the rear window it looks like the seal and bolts just need to be replaced and re-aligned. Would love to see if anyone else has done anything like this in any hopes i can do it myself before taking it to the dealership for an outrageous price.
Here are photos of how the rear window is sitting with missing bolts
Here are images of the side windows (t handles are rusted beyond use and gas props are starting to rust.


Thank you in advance! Id like to replace all the handles anyway because I would like to be able to lock the, but not sure where to get them.

I got t handle for my truck at a local locksmith

 

Here are the handles for the side windows, they have a threaded back instead of the square peg like the rear window ones.
I would check with Leer first and see if you could get all 4keyed alike.

If yours are rusted you might also be missing the little metal bracket for the side window which keeps the lock from spinning. I think my local locksmith also had those handy
