what are you trying to do, then we can tell you, what car do you have?.......what YEAR most importantly, and what YEAR parts are you trying to install, you cant go using a 91 ls tranny on a 95 integra cause of the hydro/cable difference, but if you had like a 94 ls tranny, you could put in on a 00 integra if you wanted, the starters and alternators are all the same for 94+b series motors, same with the starters.....
