Ok thatís handy, I mention that I was looking at 2002 gt diff for $500. Well not anymore the owner sold it, so yesterday I saw 2000 Gt stick. Is a 2000 GT 100% compatible with my 2001? or there are some differences. Thanks I want to have it done for this weekend so I can take it to a dyno. However thatís not now, first things first. Thank you.
