I wanted to test my knowledge level and the 5" "theory" against the following two threads. The first thread demonstrates the hole for the lower body molding for rear cab is approx. 8 1/8", and the molding for the upper molding for rear cab is approx. 23 13/16"...
Word is the real VALUE of that 30" mark in the assembly manual is it's 25" from the body.
Looking at the second thread of the assembly manual: The top molding hole locations are 1.07" and 1.09" from the 25" line (reads 30"). I'll call it 1.08", therefore the hole should be 23.92" from the bottom.........Pretty darn close to 23 13/16", and that was just from a picture and bad eyes. So I think it's safe to say that
YES, that 30" line is a 25" reference point. My only question would be, is that from the ridge of the cab that lies underneath or is it from the lower cab body? I think I know who to ask.
In some ways these measurements are just a guide. There's a video (
https://www.youtube.com/watch?v=5JQYAEa0OGw) that shows the upper is based on the molding that sits above the door lock. From there you tape everything on for temporary and just eye ball it.
Then you have to consider should that bed and/or cab be off.......there's no substitute for how it looks, and those assembly specs. may not be the answer. Makes me think I need to have the rear leafs arced so they're even. That or buy new ones. One side is 1/4" off. Be a lot simpler w/o the moldings.
