https://www.my.is/forums/f221/diy-lsd-differential-pumpkin-swap-521817/ Found most of the required info here, build shows an IS300 but much of the same applies. For those interested the M58 is a straight swap, definitely a two person job though (when you only have axles stands and a regular jack).

Hi all, new poster. Have had my IS200 about 6 months now and would like to swap in a factory LSD (M58). I believe I've found all the necessary one use bolts required and have a source for them and the diff. It looks to be a straight swap of open diff currently in my SE to the factory unit from a sport model. Is this the case? I'm looking to see if anyone has done the same previously and has any advice on it? Bit apprehensive as I've not swapped diffs before. Thanks.
