Question, how are all these trannys mounted? 
  
Who is using a S13 Tranny, and who is using the RB RWD Tranny? 
  
In addition, what ways are both trannys mounted? 
  
(Also, from what I see, you can use the Z31 RB Motor Mounts, or the Z31 V6 Motor Mounts, are these two mounts different, because i know the 200ZR was the Z31 powered by the RB20DET in some countries.)
