Is there any chance that a 3.25 LS from a 535 will NOT fit a 528e? Maybe it is me just being tired, but the first time I raised this thing up into the well, the holes didn't seem to line up. They're both side by side in the garage now, and I cannot measure any difference at all, and they look the same. Both have 1 218 411 on the side by the input, but the 3.25 has a 'c' after it, and the 2.93 has a 'b.' Dave.
