DT, I plan to post a project on my customisation of the upgrade kit, but as a fast track, all you need is some sort of lifting mechanism that could be shop made using a button nut, which will satisfy both the fast positioning and micro adjustment in the one tool,

(pictures are a round and hex nut, and are 15.875mm but the one supplied in the kit is 12.7mm)... and this leveling process,

If your first cut is too short... Take the second cut from the longer end... LBD
