The whole diff mounts right up correct?

 

Bolts up exactly...no modifications needed. It's a great mod!

 

Dealer, supraforums, junk yard or eBay are your best shots. You are going to be looking around $1000 used. It's a bolt on for the most part. If you know what your doing you can just swap internals with a auto tt supra and throw in new bearings while your in there, you should be able to find just the internals for about $400 and then order bearings from Carson toyota.

 

I think Swelle lexus has one for $1100
