Bulkhead window install on Custom 2014

[KT2023]

Hi, I was wondering if anyone could suggest somewhere I could get a window for the bulkhead of my custom 2014.
I looking to make it in to a day van and wanted to install a sliding window instead of removing the bulkhead for some ventilation and light.

The van obviously has an indentation where one could potentially go but I'm having trouble trying to source something that would fit it.

TIA

I don't know much about these, could you ask someone to customize one?
