SRS CODES

I bought a 2003 that had bumped into something and a previous owner didn't replace and reset the airbags and seat belt.

Codes before I replaced the front airbags:
B0103 short D squib to battery voltage
B0107 short in P squib circuit (ground)
B0136 open in P/T left hand circuit
B0101 open in D squib circuit
B0106 open in P squib circuit
B0131 open in P/T right hand circuit

Code after replacing front airbags:
B0136 open in P/T left hand circuit

From what I've gleaned online I'm thinking I need to replace the from seatbelts. I thought I'd check here first to see if anyone has dealt with this issue and can tell me if I'm on the right path.

Thanks in advance.

 

The side airbags in the seats appear to be in tact and still plugged in to the SRS harness.
