While we don't have an install video for the exact pin box model you referenced part # LC328329 we do have install videos for similar cushioned pin boxes that fit the same application (Lippert 1621) which would work great as an install guide. I attached a video link to this page for the similar 5th Airborne part # 5AB-E1621-610 for you to check out. This will walk you through the important steps that are the same like the removal of the old box and the install of the new one.

For the torquing of the bolts you'll need to use the following as a guide:
1/2 inch Bolts GR5 90 ft-lbs
5/8 inch Bolts GR5 150 ft-lbs
3/4 inch Bolts GR5 275 ft-lbs
