Paclock's serious hasp for van rear doors, installation.

I installed a huge Paclock hasp and puck lock on the rear doors. This lock is seriously more secure than many "popular" brands van door locks. Please feel free to ask any questions, as I feel like some of the tweaks that i had to make towards the end of the installation are not explained very well in the video. I bought 2 of these but I don't think I can make one work for the slider.
