I have a 1988 325iC and I'm trying to figure out what friggin diff it has. It was originally an automatic, so I believe it should be a 4.10:1, but I've never seen a tag like this before... The numbers on the tag are 1141A4578S. Anyone have a clue? I think it may have been swapped once before and this may be a reman unit or something? I was wondering if anyone has run across numbers like this before. I can find out the ratio from counting and dividing, yes, but it would be nice to get a story about whether it's stock or not... HELP!!!
