[MR2] MK2 3SGTE Question

[Aaron Bunch]

The rear LSD is an extremely rare option in the US. It was not standard. 

Buy the cleanest most virgin ST185 you can find. I've seen lots of them. Most are pretty slutted out. Dave Hawkins has a great one. He ignored the mileage and bought based on condition/originality.
