thats nice when you have a pattern to go on. I was saying you can measure the height of your mounts from the bottom of the frame to the top of the mount, instead of from the top of the frame which as you say does get shorter towards the front mounts. the reason the rear cab mounts are made "higher" is because the cab floor is not perfectly flat, it is higher in the rear than the footwell. I noticed this same thing on the mounts I designed for my 41, the rear mounts are 3/4" higher, I used a straightedge and measured up to the floor


I havent ever put any rake on the cab in relation to the frame or running boards so you might be in territory I have no experience with. I always level the frame and then mount the cab level with respect to the frame, then the running boards level with respect to the cab and frame. in my opinion this makes mounting the bed easier because you dont need angled spacers, the rear section of the frame is level too.
