[Shadow Stranger]

In the file CryptA.bol I found entries for the two Jindols:
Offset 1,600, I077, [Item 77, Warrior's Jindol], 0, 3, 107, 71, 0, 64, 63, 68, 0, 198, 222, 70
Offset 1,664, I078, [Item 78, Wizard's Jindol], 0, 3, 107, 71, 0, 64, 63, 68, 0, 232, 172, 197
Both Jindols would seem to have about the same X and Z coordinates, where Z is the height. They should differ mainly in the Y coordinate. Entries differ in the fourth offset and in the last three, hence the last three are probably the Y coordinate.

In the second room inside the Crypt there is a skull lying on a table. Adding +1 to the 198 made the skull disappear, presumably its position was shifted well south of the relevant room. Adding +18 to the 237 moved it a few feet south of the table. Y coordinate would seem to be 112, 59, 237, 198.
Offset 29,504, I251, [Item 251, Skull], 40, 22, 45, 199, 0, 160, 53, 69, 112, 59, 237, 198

Going from the right of each four byte group, adding 1 to the second number moves the item very roughly 6" in apparent terms. Thus changing the 45 to a 50 moved the skull a few feet. (Left not right too.)
40, 22, 45, 199,
0, 160, 53, 69,
112, 59, 237, 198
