John:

Generally, the early XJ rears may have posi and have better ratios than the later ones which as you say are generally "long" ratios and open rears. I have used 2.88 and 3.08 rears with a Richmond 4+1 (5th is 1:1) and found it, for my purposes, to be a good setup. The most recent rear that I scrounged was out of a late XJS V12. It had posi, but a 2:88 ratio which I had swapped out for a 3.77. This is behind a Tremec TKO.
