Sorry to hear about your illness. I hope the treatments are going well.
New guy here reading this thread in entirety! My module is an '02 but appears identical to yours. I have front/rear lightbars to remove. I was planning to cut down the center hump like you did, but if I had the bolt location dimensions, I could just holesaw around the bolt heads.
Is there any way you could provide the center-to-center bolt locations? I would do some "investigative" drilling to find the exact center of the bolt heads.
Either way, you have been a great benefit to my project.
Saginaw pump pressure output on P/S conversions can be altered. Too much pressure and all road feel is lost vs too little and hard steering. There’s a spring and rod which control it... Likely similar for our steering. Too much pressure and steering boxes will eventually sufffer with big tires.
