OK, I have read other posts here about keeping tire sizes the same on awd and it seems none are conclusive...........The car I bought was actually a 1993  instead of a 1992 Legacy wagon with 223000 miles..The car is a FIVE SPEED and It runs GREAT. Only a few issues... 
  
1) Park brake button is GONE ... 
  
2)Both rear tires are gone on the inside they may have been rotated from the front? 
  
Do I need to replace ALL four tires at the same time? 
  
3)Right rear brake is scrubbing(probly just needs a brake job,rotor is a little rusty) 
  
4)Driver shoulder belt thing does not move in the track.  
  
How or where do I fix the seat belt thing ? 
  
5) Shifter needs bushings....Where to buy them? 
  
  
  
Thats all I can think of now..Any responses are GREATLY appreciated!! Thanks in advance
