1985 D150 "Mr. Curtis" race truck with a 2015 6.4

If it does still fit when i'm done narrowing the '05s Ram crossmember, i would like to use the steering rack of a '05 Ram SRT-10 (shortbed, that's important).
It's been modified for a quicker ratio by SRT.

If it does not fit any more, maybe a custom steering rack is in order or i can find something else that works with the distances between the inner UCA/LCA pivot points.
I have a (legal) copy of PerformanceTrends SuspensionAnalyzer 2.4 that i will feed with the data (read: each suspension pivot points location) and work out a geometrically proper solution.

As for the line pressure:
I think every pump can be disassembled and modified to either increase or decrease pressure. For example on (early model) Saginaw pumps, all you had to do was change the shim behind the spring in the pressure valve to (in most cases) decrease the pressure so there is more "feel" in the steering.
While this is the ultimate route i would want to go - because i want to be able to just buy stock components to replace broken stuff - i would not have a problem tearing into a pump and see what could be done to adapt it.

The pressure lines are probably another custom job...
