You would have to get one from overseas. Unless, someone can prove me wrong lol. The closest thing is a 300zx but, the problem is it will be a lhd rack. You need a rhd R32 rack.
For an example

Edit: (I didn't see it before but, I guess he only does pickups!!!)
Which according to that a R33 or silvia will work, but I would definitely look around on the interwebs.
Another idea is to have it rebuilt, but I have no idea how that process goes.
