I think that you are over-thinking it.
The front is a compromise between caster and pinion. Tilt the pinion up too far, and the caster will be so low that you won't ever want to drive it. Your lift mfg provided fixed length arms to bring the caster/pinion to that acceptable 'compromise' level. Get the new shaft and drive it, and then decide if you need to throw more money at it.

Ok... So generally the lowers are set to 23" to 231/8 to set wheel base and the uppers are used to raise the pinion or lower for caster.
I am assuming the lowers are at that (231/8") or close with the measurement you have.
I would still remove a arm or contact BDS. Check to see what they measure.
If the lowers are at 23" or so. Adjustable uppers will help get the pinion up.
