XJS and the ABS system that has failed. 1992Model with 56000 miles

With the acquisition of my 92 XJSC, I now have 3 [2 Buick Reattas] cars with the dreaded Teves ABS system. The conversion of the Teves III to the IV seems like a doable, if not and almost necessary modification, particularly since the substitution of the LT1 for the V12 created a much more accommodating engine bay.
I am not very sharp on Teves theory, but good at following directions.
As this is a such a worthwhile modification, could someone [wink: Kirbirt or Lockheed] who has done this perhaps take the time to make a step-by-step outline of the process and a list of new/donor parts [although Lockheed has pretty much did that ([xj-s] Conversion From Teves III to Teves IV)] that have to be gathered up for the job?
